How to Make Cheddar Biscuit Breakfast Casserole : Ultimate Comfort Dish
Step 1: Prep Your Baking Dish and Oven
Start by preheating your oven to 375°F (190°C) and greasing a 9×13-inch baking dish. This ensures nothing sticks and gives you those beautiful, clean slices later. A little prep here sets the stage for easy assembly and a perfectly baked Cheddar Biscuit Breakfast Casserole : Ultimate Comfort Dish.
Step 2: Brown the Sausage
In a large skillet over medium heat, cook your breakfast sausage until it’s browned and crumbly. This is where a lot of the flavor magic begins! Once it’s cooked, scoop it out and let it drain on a paper towel, but keep about a tablespoon of that flavorful grease in the pan.
Step 3: Sauté the Veggies
Add your olive oil to the same skillet, then toss in the diced onion, red bell pepper, and green bell pepper. Sauté everything for about 5 minutes, stirring occasionally, until the veggies are softened and fragrant. They’ll pick up little bits of sausage flavor and become even more delicious.
Step 4: Prep the Biscuits
Open your tube of refrigerated biscuits and cut each one into quarters. Scatter these biscuit pieces evenly across the bottom of your prepared baking dish. This is what gives the Cheddar Biscuit Breakfast Casserole : Ultimate Comfort Dish its signature fluffy layers.
Step 5: Layer Sausage, Veggies, and Cheese
Next, layer the cooked sausage and sautéed vegetables over the biscuit pieces. Sprinkle 1 1/2 cups of your shredded sharp cheddar cheese over everything, making sure it gets into every nook and cranny for maximum cheesy goodness.
Step 6: Whisk Eggs and Seasonings
In a large bowl, whisk together the eggs, whole milk, garlic powder, smoked paprika, salt, and black pepper until smooth and well combined. This creamy mixture is what brings everything together and bakes into the irresistible custard filling.
Step 7: Assemble and Bake
Pour your egg mixture evenly over the biscuit, sausage, and veggie layers. Top it all off with the remaining 1/2 cup of cheddar cheese. Slide the dish into your preheated oven and bake uncovered for 35 to 40 minutes, or until the eggs are set and the top is gloriously golden.
Step 8: Rest and Garnish
Once baked, let the casserole rest for about 5 minutes out of the oven—this makes it easier to slice and serve. Sprinkle with chopped fresh parsley for a burst of color and freshness, and get ready to dig in!
