Breakfast Casserole with Biscuits Guide

How I Fell in Love with This Recipe

Hey there, let me tell you—I’m obsessed with breakfast food. There’s just something about waking up to the smell of warm, cheesy, and savory comfort food that makes me feel like the day is already off to a perfect start.

Now, I’ll be honest—I’m not someone who enjoys spending hours in the kitchen every morning. I love delicious food, but I also love my sleep, so I’m always looking for quick, easy, and satisfying breakfast recipes. That’s how I discovered this Breakfast Casserole with Biscuits—a game-changer for me!

I first made this recipe on a lazy Sunday morning when I wanted something hearty but didn’t want to spend forever cooking. I had a can of refrigerated biscuits, some breakfast sausage, and of course, eggs and cheese (because cheese makes everything better, right?). I thought, “What if I just throw all these ingredients into one dish and bake it?”

Well, let me tell you—the result was pure breakfast magic. 😍

The biscuits baked up fluffy and golden, the eggs set perfectly, the sausage added that savory goodness, and the cheese melted into an ooey-gooey dream. After that, I was hooked!

This casserole is now my go-to breakfast for so many occasions—whether I’m meal-prepping for the week, hosting brunch with friends, or just craving something warm and filling..

Why This Casserole is a Game-Changer

If you’re anything like me, you want breakfast to be delicious without being a hassle. That’s why this casserole checks all the boxes for a perfect morning meal.

✔ Super Easy to Make – Everything goes into one dish, and the oven does the work!
✔ Perfect for Meal Prep – Make it once, eat it all week.
✔ Feeds a Crowd – This casserole is a hit at brunch gatherings and holiday mornings.
✔ Customizable – You can switch up the ingredients to match your cravings!
✔ Comfort Food Perfection – Every bite is warm, cheesy, and satisfying.

Seriously, this is one of those no-fail recipes that will become a regular in your kitchen. I’ve made it countless times, and it always turns out amazing!

What Makes This Recipe Different?

I’ve tried a lot of breakfast casseroles before, but this one stands out for a few reasons:

1️⃣ The Biscuits Create a Perfect Base
Instead of using bread cubes or hash browns, this recipe uses biscuits. When baked, they turn into flaky, golden, buttery layers that soak up the egg mixture just right. Every bite has the perfect balance of soft, fluffy texture with a slightly crispy edge.

2️⃣ It’s Loaded with Cheese (Because Cheese = Happiness)
I’ll be honest—I don’t do “light cheese.” I love my casseroles extra cheesy, so I use a blend of cheddar and mozzarella. You can even throw in pepper jack or Swiss if you want to get fancy!

3️⃣ Customizable for Any Taste!
One thing I love about this casserole is that it’s never the same twice. Some mornings, I make it spicy with jalapeños. Sometimes, I pack it with extra veggies. And when I’m feeling extra indulgent? Bacon AND sausage, baby! 😋

Step-by-Step Instructions – How I Make the Best Breakfast Casserole with Biscuits

This is where the magic happens! Let me guide you through each step so you can get the best results every time.

🥣 Step 1: Preheat the Oven & Prepare Your Baking Dish
Before I even touch my ingredients, the first thing I do is preheat my oven to 375°F (190°C).

🔹 Why does this matter? If the oven isn’t hot enough, the biscuits won’t bake properly, and you could end up with a soggy or undercooked casserole. Believe me, I found that out the hard way!

Next, I grease my 9×13-inch baking dish. You can use:
✔ Butter (adds flavor!)
✔ Cooking spray (for convenience)
✔ Olive oil (if you prefer a lighter option)

✅ Pro Tip: I sometimes line my dish with parchment paper to make clean-up even easier!

🥓 Step 2: Cook the Sausage (Or Your Protein of Choice)
While the oven preheats, I cook the sausage in a skillet over medium heat. It usually takes about 7-10 minutes to get it fully browned and cooked through.

Here’s what I do:
1️⃣ Heat a large skillet over medium heat.
2️⃣ Add the breakfast sausage (I break it up into crumbles with a spatula).
3️⃣ Stir occasionally until it’s fully browned and no longer pink.
4️⃣ Drain the excess grease by placing the cooked sausage on a paper towel-lined plate.

✅ Pro Tip: If using bacon, I cook it until crispy, then chop it into small pieces. If using ham, I dice it and sauté it for a few minutes to bring out its smoky flavor.

🥖 Step 3: Cut the Biscuits & Arrange in the Dish
Now for my favorite part—the biscuits!

Here’s what I do:
1️⃣ I open the can of refrigerated biscuits (which always makes me jump because of the pop! 😂).
2️⃣ Using a sharp knife, I cut each biscuit into four equal pieces (quarters).
3️⃣ I spread the biscuit pieces evenly across the bottom of my greased baking dish.

🔹 Why cut them? Whole biscuits are too thick and won’t bake evenly. Cutting them allows the egg mixture to soak into them, creating a perfect fluffy texture!

✅ Pro Tip: I don’t overlap the biscuits too much—I want them to be evenly distributed for the best results!

🥚 Step 4: Prepare the Egg Mixture
This is what binds the whole casserole together and makes it creamy and delicious.

Here’s how I do it:
1️⃣ In a large mixing bowl, I crack 6 large eggs.
2️⃣ I add 1 cup of milk (I use whole milk for richness).
3️⃣ I sprinkle in salt, black pepper, garlic powder, onion powder, and paprika.
4️⃣ If I want a little kick, I add a few dashes of hot sauce! 🌶️
5️⃣ I whisk everything together until it’s completely smooth.

✅ Pro Tip: Whisk really well to make sure the eggs and milk are fully combined—this ensures even cooking.

🧀 Step 5: Assemble the Casserole
Now comes the fun part—putting it all together!

Here’s how I layer everything:
1️⃣ Biscuits first – They create the perfect base.
2️⃣ Sausage (or bacon/ham) next – I sprinkle it evenly over the biscuits.
3️⃣ Pour the egg mixture – I carefully pour the whisked eggs over everything, making sure it soaks into the biscuits.
4️⃣ Cheese on top – I sprinkle a mix of cheddar and mozzarella (because more cheese = more happiness! 🧀).

✅ Pro Tip: If I’m adding veggies, I mix them into the egg mixture before pouring it over the biscuits.

🔥 Step 6: Bake Until Golden & Set
Now, I place my casserole in the preheated oven (375°F / 190°C) and let it bake for about 30-35 minutes.

🔹 How do I know when it’s done?
✔ The top is golden brown and slightly crisp.
✔ The eggs are fully set and not jiggly in the center.
✔ A knife inserted in the middle comes out clean.

✅ Pro Tip: If the top is browning too fast but the center isn’t done, I loosely cover it with aluminum foil and bake for a few extra minutes.

⏳ Step 7: Let It Rest Before Serving!
This is the hardest part—waiting to eat it! 😩 But trust me, letting the casserole sit for 5-10 minutes makes a HUGE difference.

🔹 Why let it rest?

It helps the eggs firm up, so the casserole doesn’t fall apart when sliced.
The flavors meld together, making each bite even better!
Once it’s ready, I grab a spatula and serve up big, warm slices. I love pairing it with fresh fruit, avocado, or even a little hot sauce! 😍

What Happens If Something Goes Wrong? (Troubleshooting Tips!)

Even though this recipe is super easy, I’ve had a few oops moments in the past. Here are common mistakes and how to fix them:

🔹 Casserole is soggy or watery?
✔ Make sure you don’t use too many veggies (especially tomatoes or mushrooms) without cooking them first.
✔ Avoid overpouring the egg mixture—just enough to coat everything!

🔹 Biscuits are still doughy inside?
✔ Check if your oven was fully preheated before baking.
✔ Bake for an extra 5 minutes if needed, and cover with foil if the top is browning too quickly.

🔹 Eggs are overcooked & rubbery?
✔ Don’t overbake! Remove it as soon as the center is set.

Customization & Variations – Make It Your Own!

One of the best things about this breakfast casserole with biscuits is how flexible it is. You can switch up the ingredients based on what you have in your fridge, your dietary needs, or just what you’re craving that day.

Whether you’re in the mood for extra meat, more cheese, a veggie-packed version, or a spicy kick, this casserole can be whatever you want it to be!

Let me walk you through all the different ways I’ve customized it so you can try them too.

🥓 Meat Substitutions – Pick Your Favorite Protein!

While I love using breakfast sausage, sometimes I like to switch things up. Here are some amazing options:

✔ Crispy Bacon – If you love bacon, this is a must-try! Cook the bacon until crispy, then crumble it over the biscuit layer before adding the eggs. It adds a smoky, crunchy texture that’s absolutely delicious.

✔ Chopped Ham – If you prefer something a little lighter, diced ham is a fantastic option. It has a slightly sweet and smoky flavor, which pairs beautifully with Swiss cheese.

✔ Turkey Sausage – Want a leaner alternative? Turkey sausage has less fat but still brings that savory, meaty flavor. Just make sure to season it well, as it’s milder than regular sausage.

✔ Chorizo – For a spicy Mexican-inspired twist, try crumbled chorizo instead of breakfast sausage. It adds rich, smoky flavors and pairs perfectly with pepper jack cheese.

✔ Shredded Chicken – If I have leftover rotisserie chicken, I’ll sometimes shred it up and mix it into the casserole. It makes the dish a little lighter while still being super filling.

✅ Pro Tip: If you’re using a leaner meat (like turkey sausage or chicken), cook it with a little olive oil or butter to keep it from drying out.

Cheese Variations – Because More Cheese = More Happiness!

I firmly believe there’s no such thing as too much cheese!While I usually stick to cheddar and mozzarella, I love experimenting with different cheeses.

Best Cheeses for This Casserole:
✔ Cheddar (Classic Choice!) – Sharp or mild, cheddar gives this casserole a rich, tangy flavor.
✔ Pepper Jack (For a Spicy Kick!) – If you like a little heat, pepper jack is a great alternative!
✔ Swiss or Gouda (Creamy & Mild) – These cheeses melt beautifully and give a smooth, buttery taste.
✔ Mozzarella (For Extra Gooeyness!) – Adds a stringy, melty texture that makes the casserole irresistible.
✔ Feta or Goat Cheese (Tangy & Unique!) – If I want something a little fancy, I’ll crumble feta or goat cheese on top—it adds a delicious creamy, tangy contrast.

✅ Pro Tip: Mix two or three cheeses together for the best flavor and texture combination! My personal favorite is cheddar + mozzarella + pepper jack.

🌿 Vegetarian Version – A Meat-Free Delight!

If you don’t eat meat or just want a lighter option, this casserole is just as amazing with veggies!

Best Vegetables to Use:

🥬 Spinach – Adds a pop of color and extra nutrients! Just sauté it first to remove excess moisture.
🍄 Mushrooms – I love using mushrooms because they add a meaty texture without the meat!
🌶️ Bell Peppers – Red, green, or yellow bell peppers add sweetness and crunch.
🍅 Tomatoes – Fresh diced tomatoes add juiciness, but sun-dried tomatoes give an intense burst of flavor!
🧅 Onions – Sautéed onions add a savory, slightly sweet taste that makes this casserole even better.
🥑 Avocado (For Topping!) – Instead of baking it in, I like to serve slices of fresh avocado on top for a creamy, fresh contrast.

✅ Pro Tip: Always pre-cook watery veggies (like mushrooms, spinach, or tomatoes) before adding them—this prevents the casserole from getting too soggy.

🥶 How to Store Leftovers – Keep It Fresh!

This casserole stores beautifully, which is why I love making extra! If you have leftovers (or if you’re meal-prepping), here’s how to store it properly:

Refrigeration (Short-Term Storage)

If I plan to eat the casserole within 4 days, I store it in the fridge.

✔ Let the casserole cool completely before storing.
✔ Transfer it to an airtight container or cover the baking dish tightly with plastic wrap or aluminum foil.
✔ Store in the refrigerator for up to 4 days.

✅ Pro Tip: If I’m meal-prepping, I like to cut the casserole into individual portions and store them in separate containers for easy grab-and-go meals!

Freezing (Long-Term Storage)

Yes—you can freeze this casserole! I do this all the time when I want a quick breakfast ready to go.

✔ Let the casserole cool completely before freezing.
✔ Wrap individual portions in plastic wrap, then place them in a freezer-safe bag or container.
✔ Label with the date so I know when I made it!
✔ Store in the freezer for up to 3 months.

✅ Pro Tip: Don’t freeze the casserole whole—cutting it into portions makes reheating much easier!

🔥 How to Reheat – Make It Taste Fresh Again!

Reheating the right way makes a HUGE difference!

Microwave (Fastest Method)

✔ Place one serving on a microwave-safe plate.
✔ Cover with a damp paper towel (this keeps it from drying out!).
✔ Heat on medium power (50-70%) for 30-60 seconds.

✅ Pro Tip: If it seems a little dry, add a splash of milk or cheese before reheating!

Oven (Best for Large Portions)

✔ Preheat oven to 350°F (175°C).
✔ Place the casserole (or slices) in an oven-safe dish.
✔ Cover with foil to prevent drying out.
✔ Heat for 10-15 minutes (or 25-30 minutes if frozen).

✅ Pro Tip: Remove the foil for the last 5 minutes to make the top crispy again!

Air Fryer (For a Crispy Finish!)

✔ Preheat air fryer to 350°F (175°C).
✔ Place a slice of casserole in the basket.
✔ Heat for 5-7 minutes.

✅ Pro Tip: The air fryer is my favorite method because it crispifies the biscuit layer while keeping the eggs soft!
