Preparation Phase & Tools to Use (Essential Tools and Equipment)

To get started with this casserole, you’ll need a few key kitchen tools:

• 9×13-inch baking dish – This is the ideal size for even baking and ample servings.
• Mixing bowls – For whisking the eggs and combining ingredients.
• Whisk – Helps incorporate air into the eggs, ensuring a fluffier texture.
• Rubber spatula – For gently folding in cheese or other mix-ins.
• Oven – A standard oven preheated to 375°F is perfect for a golden top and evenly cooked center.

Each of these tools plays a role in making the process smooth and the final dish come out perfectly cooked.

Preparation Tips

For the best results, use cold biscuit dough to help the base rise and remain flaky during baking. Shred your cheese fresh rather than using pre-shredded, as it melts more smoothly and adds a richer flavor. Let the casserole sit for about 5–10 minutes after baking to allow the layers to settle, making it easier to slice and serve. If you’re adding cooked meats or veggies, make sure they’re well-drained to avoid excess moisture, which can make the biscuit layer soggy.

Ingredients for this Cheddar Bay Biscuit Egg Breakfast Casserole

• 1 package (11 oz) Cheddar Bay biscuit mix (such as Red Lobster brand)
• 1/2 cup cold unsalted butter (for biscuit mix)
• 1 cup shredded sharp cheddar cheese (plus extra for topping)
• 6 large eggs
• 1/2 cup whole milk or heavy cream
• 1/4 teaspoon garlic powder
• 1/4 teaspoon onion powder
• Salt and pepper to taste
• 1/4 cup chopped fresh parsley (optional, for garnish)
• Non-stick spray or butter (for greasing the baking dish)

Optional Add-ins:

• 1/2 cup cooked bacon or sausage crumbles
• 1/2 cup sautéed onions or bell peppers
• 1/4 teaspoon smoked paprika (for a subtle kick)

Step 1: Prepare the Biscuit Base

Preheat your oven to 375°F (190°C). Grease a 9×13-inch baking dish with butter or non-stick spray. In a mixing bowl, prepare the Cheddar Bay biscuit mix according to the package instructions, typically by cutting in cold butter and mixing until dough forms. Press the biscuit dough evenly into the bottom of the baking dish to form the base layer.

---

Step 2: Whisk the Egg Mixture

In a separate large bowl, crack the eggs and whisk them until light and fluffy. Add the milk or cream, garlic powder, onion powder, salt, and pepper. Whisk again until the mixture is smooth and well combined. This ensures the eggs bake up light and tender.

---

Step 3: Add Cheese and Optional Fillings

Fold in 1 cup of shredded cheddar cheese into the egg mixture. If you’re using bacon, sausage, sautéed vegetables, or herbs, now is the time to add them. Mix gently to distribute everything evenly.

---

Step 4: Assemble the Casserole

Pour the egg mixture evenly over the biscuit base in the baking dish. Use a rubber spatula to spread the mixture so it covers all areas. Sprinkle additional shredded cheese on top for that golden crust.

---

Step 5: Bake to Perfection

Place the casserole in the preheated oven and bake for 30–35 minutes, or until the top is golden brown and the center is set. You can test doneness by inserting a toothpick into the center — it should come out clean.

---

Step 6: Let It Rest and Garnish

Once out of the oven, allow the casserole to rest for 5–10 minutes. This makes it easier to slice and enhances the flavor. Sprinkle freshly chopped parsley over the top before serving for a pop of color and freshness.

Notes

This casserole is incredibly flexible. You can make it vegetarian by skipping the meat or spice it up with jalapeños or hot sauce. For a richer flavor, consider using half-and-half instead of milk. If you’re preparing it the night before, assemble the casserole and cover it tightly with foil; refrigerate overnight and bake fresh in the morning.

Watch Out for These Mistakes While Cooking

• Overmixing the biscuit dough – This can make the base tough instead of tender and flaky.
• Not greasing the baking dish – It can lead to sticking and difficulty serving.
• Using too much liquid – The eggs should be creamy but not watery; excess liquid can prevent proper baking.
• Baking at too high a temperature – This could brown the top too quickly while leaving the center undercooked.
• Skipping the rest time after baking – This allows the casserole to set, making slicing and serving easier.

---

Storage Instructions

Let the casserole cool completely before storing. Cover the baking dish tightly with foil or transfer slices to airtight containers. Refrigerate for up to 4 days. To reheat, microwave individual portions or warm the entire dish in the oven at 300°F until heated through. For freezing, slice into portions, wrap tightly in plastic and foil, and store in a freezer-safe container for up to 2 months.
