Step‑by‑Step Instructions for Cheddar Biscuit Egg Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). This ensures that your Cheddar Biscuit Egg Casserole will cook evenly throughout. While the oven warms up, gather your baking dish and greasing spray or butter to prepare for the dough.
Step 2: Combine Dry Ingredients
In a large mixing bowl, whisk together the Cheddar Bay biscuit mix, baking powder, salt, and black pepper. Make sure the ingredients are well combined for an even dough texture. This step is essential for creating that light, fluffy biscuit base that will hold your casserole together.
Step 3: Add Milk to the Dough
Gradually pour in the milk while stirring the dry mixture until a soft dough forms. You want the consistency to be smooth and somewhat sticky, but not runny. This will provide the perfect base for the flavors to build upon in your casserole.
Step 4: Prepare the Biscuit Base
Spread the biscuit dough evenly into a greased baking dish, using your fingers or a spatula to create an even layer. This forms the foundation of your Cheddar Biscuit Egg Casserole. Aim for a thickness of about half an inch, as this ensures a delicious, fluffy base after baking.
Step 5: Layer with Cheese and Bacon
Sprinkle shredded cheddar cheese generously over the biscuit layer, followed by the chopped turkey bacon. The cheese will melt perfectly into the biscuit base, enhancing the flavor, while the bacon adds a savory depth. Feel free to customize with your favorite cheese or protein.
Step 6: Whisk the Egg Mixture
In a separate bowl, whisk together the eggs, diced bell peppers, garlic powder, and chopped green onions until well combined. This mixture will provide the protein and creaminess that bring your casserole to life. Make sure to beat the eggs well for a light and fluffy filling.
Step 7: Pour Egg Mixture Over Layers
Carefully pour the egg mixture over the layers of cheese and biscuit base, ensuring an even distribution. This allows the eggs to nestle between the layers, creating a cohesive and flavorful Cheddar Biscuit Egg Casserole. Watch for any pooling, which can indicate unevenness.
Step 8: Bake the Casserole
Place the baking dish in the preheated oven and bake for 35 minutes, or until the eggs are fully set and the top is golden brown. You’ll know it’s done when a knife inserted in the center comes out clean. The aroma wafting through your kitchen will be simply irresistible.
Step 9: Cool and Serve
Once baked, remove the casserole from the oven and let it cool for a few minutes. This helps the layers firm up, making it easier to slice. Serve warm, and enjoy the delightful combination of flavors in your Cheddar Biscuit Egg Casserole with family and friends!

Make Ahead Options
This Cheddar Biscuit Egg Breakfast Casserole is an excellent choice for meal prep enthusiasts! You can prepare the entire casserole up to 24 hours in advance by assembling it completely, covering it tightly with plastic wrap, and refrigerating overnight. To maintain quality, avoid adding the egg mixture until just before baking; instead, whisk it together and pour it over the layers right before placing it in the oven. If you have leftovers, store them in an airtight container in the fridge for up to 3 days. When you’re ready to serve, simply bake it in the preheated oven for about 35 minutes until cooked through, and enjoy a warm, hearty breakfast with minimal morning fuss!
Tips for the Best Casserole
Customize with Ease: Use your favorite proteins or veggies to create a personalized Cheddar Biscuit Egg Casserole; think spinach or mushrooms for an added twist!
Don’t Overmix: Mix your biscuit dough just until ingredients are combined to prevent a tough texture. A little lumpiness is perfectly fine!
Check Doneness: Ensure your casserole is fully set before removing it from the oven; a knife inserted should come out clean for the best slices.
Let It Rest: Allow the casserole to cool slightly after baking. This helps the layers firm up and makes for easier and neater slices.
Store Leftovers: Keep any remaining casserole in an airtight container in the fridge for up to three days, so you can enjoy your delicious creation longer!
