What Ingredients You Will Need

This Easy Cheesy Biscuit Breakfast Casserole uses straightforward, wholesome ingredients to bring you a hearty breakfast without any complicated steps. Most are pantry staples, and some can be swapped depending on your preferences or dietary needs.

• Refrigerated biscuit dough (1 can, about 10-12 biscuits): Using store-bought flaky dough saves time and adds buttery layers.
• Breakfast sausage (12 oz / 340 g): Ground pork sausage works great; mild or spicy based on your taste.
• Large eggs (6, room temperature): Binds everything together with a rich, custardy texture.
• Milk (1 cup / 240 ml): Whole milk or 2% for creaminess (dairy-free milk works if needed).
• Shredded cheddar cheese (2 cups / 200 g): Sharp cheddar adds bold flavor and melts beautifully.
• Cottage cheese (optional, 1/2 cup / 120 g): Adds creaminess and a slight tang (look for small-curd for best texture).
• Green onions (2, sliced): Freshens the dish with a mild onion bite.
• Salt (1/2 tsp) and black pepper (1/4 tsp): Balances and enhances all the flavors.
• Butter (1 tbsp, melted): For greasing the baking dish and adding richness.

For substitutions, you can use turkey sausage for a leaner option or vegetarian sausage if preferred. Gluten-free biscuit dough works well here to make the recipe gluten-free. When in season, fresh herbs like parsley or chives can be swapped in place of green onions for extra brightness. I personally love using Tillamook shredded cheddar for the best melt and flavor, but any good-quality sharp cheddar will do.

Equipment Needed

• Baking dish: A 9×13 inch (23×33 cm) casserole dish is perfect for even cooking.
• Large skillet: For browning the sausage—nonstick or cast iron works great.
• Mixing bowl: To whisk eggs, milk, and seasonings together.
• Whisk or fork: For mixing the egg mixture smoothly.
• Measuring cups and spoons: For precise ingredient amounts.
• Rubber spatula or spoon: For folding ingredients gently.

If you don’t have a cast iron skillet, a heavy-bottomed nonstick pan will do just fine for browning sausage. For a budget-friendly option, glass casserole dishes work as well and don’t retain odors. Just make sure to grease the dish well with butter to prevent sticking. I recommend keeping your biscuit dough chilled until ready to use, as it handles better that way.

Preparation Method

1. Preheat your oven to 350°F (175°C): This ensures everything bakes evenly and the biscuits get golden brown.
2. Prepare the sausage: In your skillet, cook the sausage over medium heat, breaking it apart with a wooden spoon. Cook until browned and no longer pink, about 6-8 minutes. Drain excess fat and set aside. (Pro tip: Don’t overcook or it will dry out in the casserole!)
3. Grease your baking dish: Use the melted butter to coat a 9×13 inch casserole dish thoroughly to prevent sticking and add a buttery base.
4. Prepare the biscuit dough: Cut each biscuit into quarters and spread evenly in the bottom of the baking dish. This creates the biscuit “crust” layer and soaks up the egg mixture beautifully.
5. Mix the egg base: In a large bowl, whisk together the eggs, milk, salt, and pepper until combined. If using, stir in the cottage cheese for extra creaminess and a slight tang.
6. Add cheese and green onions: Fold in 1 1/2 cups (150 g) of shredded cheddar and the sliced green onions into the egg mixture.
7. Layer the casserole: Sprinkle the cooked sausage evenly over the biscuit pieces in the baking dish. Pour the egg and cheese mixture over the top, gently pressing down to ensure the biscuit pieces soak up the custard.
8. Top with remaining cheese: Sprinkle the remaining 1/2 cup (50 g) of shredded cheddar on top for a bubbly golden crust.
9. Bake: Place in the oven and bake for 35-40 minutes, or until the eggs are set and the top is golden brown. You can test doneness by inserting a knife into the center; it should come out clean.
10. Cool slightly before serving: Let the casserole rest for 5 minutes to set up—it makes slicing easier and flavors meld beautifully.

Keep an eye on the casserole during the last 10 minutes; if it’s browning too quickly on top, tent with foil to avoid burning. And hey, if you want a little extra crispiness, you can broil for a minute or two at the very end—just watch it like a hawk!

Cooking Tips & Techniques

Here are some tips I’ve learned through a few too many trials (and a couple of tasty mistakes):

• Don’t overmix the egg custard: Whisk just enough to combine. Overmixing can lead to a rubbery texture.
• Use cold milk and room-temp eggs: This helps the custard blend smoothly without curdling.
• Brown sausage thoroughly but keep it juicy: Overcooked sausage gets dry and tough after baking.
• Cut biscuits into quarters: This allows the custard to soak through nicely, creating a tender, flavorful base.
• Let it rest after baking: The casserole firms up and slices better once cooled briefly.
• Multitasking tip: While the sausage cooks, preheat the oven and prep your eggs to save time.
• For even cooking: Spread ingredients evenly and press biscuit pieces lightly into the egg mixture.

I once skipped browning the sausage (don’t do that!) and ended up with a bland, greasy casserole. Trust me, the sausage flavor is the backbone here, so don’t rush this step. And if you want a little extra pop, sprinkle some smoked paprika or red pepper flakes into the egg mixture.

Variations & Adaptations

This casserole is super flexible, so you can tweak it to your liking without losing any of the goodness.

• Vegetarian version: Swap sausage for sautéed mushrooms, diced bell peppers, or a plant-based sausage substitute.
• Low-carb adaptation: Use almond flour biscuit dough or make a crustless version by skipping the biscuits and adding extra cheese and veggies.
• Seasonal twist: Add fresh spinach or kale in spring, or toss in diced butternut squash or sweet potatoes in fall for a hearty touch.
• Cheese variations: Try pepper jack or mozzarella instead of cheddar for a different flavor profile.
• Herb boost: Add fresh rosemary, thyme, or parsley for an herby aroma and extra depth.

Personally, I’ve made it using turkey sausage and tossed in chopped zucchini for a veggie boost—worked like a charm and was gobbled up quickly! You can also bake individual portions in muffin tins for grab-and-go breakfasts or freezer-friendly meals.

Serving & Storage Suggestions

This Easy Cheesy Biscuit Breakfast Casserole is best served warm, straight from the oven, with a light sprinkle of fresh herbs or extra green onions on top for color. It pairs beautifully with fresh fruit, a crisp green salad, or even a cup of your favorite morning coffee or tea.

To store leftovers, cover the casserole tightly with foil or plastic wrap and refrigerate for up to 3 days. When reheating, microwave individual portions for 1-2 minutes, or reheat the whole dish in a 350°F (175°C) oven for about 15 minutes until warmed through.

If you want to freeze the casserole, prepare and bake it as usual, then cool completely. Wrap tightly and freeze for up to 2 months. Thaw overnight in the fridge before reheating as above. Flavors actually deepen after resting, so leftovers can be even tastier!

Nutritional Information & Benefits

Nutrient	Amount

For those watching carbs, swapping biscuit dough for a low-carb or gluten-free alternative works well. The dish is naturally gluten-containing unless you use special biscuits.

From a wellness perspective, this recipe feels indulgent yet offers a good dose of protein to fuel your day, especially when paired with fresh fruit or veggies.
