Honestly, I can’t resist these biscuits with eggs! I love how easy it is to whip up, and my family always asks for seconds. Add some fruit on the side, and you’ve got a happy start to the day!
Key Ingredients & Substitutions
Cheddar Bay Biscuit Dough: This recipe shines with the quick and easy biscuit dough. While I love the buttery flavor from the refrigerated dough, you can also make homemade biscuits if you prefer a more scratch-made option.
Eggs: Large eggs are a must for this dish, as they provide the base for the casserole. For a lighter version, you can use egg whites or egg substitute. Just keep in mind it might change the texture a bit.
Shredded Cheddar Cheese: Cheddar not only complements the biscuits well but also melts beautifully. You could substitute with Monterey Jack or Pepper Jack for a little kick. Don’t forget to shred your own cheese for better melting!
Breakfast Sausage or Bacon: This ingredient adds protein and extra flavor. Feel free to switch it out for turkey bacon or leave it out for a vegetarian option. You can also use veggies like bell peppers or spinach in place of meat.
Green Onions: They add a nice freshness to the casserole. If you don’t have them, diced regular onions or chives can work as a substitute!
How Do I Ensure My Casserole is Fluffy and Tasty?
To achieve a fluffy and flavorful casserole, attention to your egg mixture is key. Whisk the eggs thoroughly with the milk and seasonings; this helps incorporate air, making the final dish light.
- Cut the biscuit dough into smaller pieces so they can soak up the egg mixture better.
- Make sure to pour the egg mixture evenly across the biscuits, allowing them to absorb the flavors.
- Don’t skip the butter drizzle on top! It creates a nice golden finish and adds richness.
- Let it rest for a few minutes after baking; this helps it set and makes serving easier.
Your casserole should come out fluffy with golden tops and delicious flavors throughout. Enjoy your cooking!

How to Make Cheddar Bay Biscuit and Egg Casserole
Ingredients You’ll Need:
For the Casserole:
- 2 cans (16.3 oz each) refrigerated cheddar bay biscuit dough (like Red Lobster-style biscuits)
- 8 large eggs
- 1 cup whole milk
- 1 cup shredded cheddar cheese
- 1/2 cup cooked breakfast sausage or bacon, crumbled (optional)
- 1/4 cup finely chopped green onions (plus more for garnish)
- 1/2 teaspoon garlic powder
- Salt and pepper to taste
- 2 tablespoons melted butter
- 1 teaspoon dried parsley or fresh chopped parsley for garnish
How Much Time Will You Need?
This delicious Cheddar Bay Biscuit and Egg Casserole will take about 10 minutes of prep time and then about 30-35 minutes to bake. So in total, you’ll need just around 45-50 minutes to have it ready to serve!
Step-by-Step Instructions:
1. Preheat Your Oven
Start by preheating your oven to 350°F (175°C). While it’s heating, take a moment to grease a 9×13 inch baking dish with butter or your favorite cooking spray to prevent sticking.
2. Prepare the Biscuit Base
Next, open those cans of biscuit dough and cut each biscuit into quarters. This will help them absorb the egg mixture. Spread the biscuit pieces evenly across the bottom of your prepared baking dish—for the perfect base!
3. Whisk the Egg Mixture
In a large mixing bowl, crack in the 8 large eggs. Add the whole milk, garlic powder, and a pinch of salt and pepper. Whisk everything together until it’s well combined and you can see it’s nice and frothy.
4. Add the Goodies
Now it’s time to add in the flavorful parts! Stir in the shredded cheddar cheese, the chopped green onions, and if you like, the crumbled sausage or bacon. This will create a deliciously cheesy and savory egg mixture.
5. Combine Everything
Pour this lovely egg mixture evenly over the biscuit pieces in the baking dish, making sure to cover those biscuits well. Don’t worry, they’ll puff up beautifully while baking!
6. Butter It Up
Drizzle the melted butter over the top of your casserole. This adds richness and helps to create that golden-brown crust on top. Yum!
7. Bake It
Place the casserole in your preheated oven and let it bake uncovered for about 30-35 minutes. You’ll know it’s ready when the eggs are set and the tops of the biscuits are golden brown and slightly crisp.
8. Let It Rest
Once done, take the casserole out of the oven and let it sit for a few minutes. This helps everything settle together, making it easier to serve!
9. Garnish and Serve
Before you dive in, sprinkle some additional chopped green onions and parsley on top for a fresh touch. Then, slice it up, and enjoy warm!
This cheesy, savory breakfast casserole is perfect for a family gathering, a brunch with friends, or a special weekend treat. Enjoy every bite of this comforting meal!
Can I Use Store-Bought Biscuit Dough?
Absolutely! The recipe calls for refrigerated cheddar bay biscuit dough, which is a quick and easy choice. You can use any brand you like, or even opt for homemade biscuits if you prefer a fresher taste!
How Do I Store Leftover Casserole?
Store any leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, simply warm it in the microwave or place it in the oven at 350°F (175°C) until heated through.
Can I Make This Casserole Ahead of Time?
Yes, you can prepare the casserole a day in advance! Just assemble it in the baking dish, cover it with plastic wrap, and refrigerate. When you’re ready to bake, remove the cover and add a few extra minutes to the baking time.
What Can I Substitute for the Eggs?
If you’re looking for an egg substitute, you can use 1/4 cup of unsweetened applesauce or a commercial egg replacer for each egg in the recipe. Keep in mind that this might slightly alter the texture, but it will still be delicious!
