Ingredients for Paleo Breakfast Casserole (Whole30-Friendly)

This wholesome casserole uses a few simple, real-food ingredients you can easily find at any grocery store.

1 lb (450g) ground sausage (sugar-free, Whole30-compliant)
2 cups (300g) shredded white potatoes or sweet potatoes
10 large eggs
1 medium onion, diced
1 bell pepper, diced
1 cup (100g) spinach or kale, chopped
1 teaspoon garlic powder
½ teaspoon smoked paprika
½ teaspoon sea salt
¼ teaspoon black pepper
1 tablespoon olive oil or avocado oil

If you want to switch things up, try making it with sweet potatoes instead of white potatoes for a slightly sweet, nutty flavor. For an alternative to sausage, use ground turkey or chicken for a leaner option.

If you love a little spice in the morning, you can also make this with chorizo and check out this Chorizo Hash Brown Casserole for a bolder take on the same concept.

Step-by-Step: How to Make Paleo Breakfast Casserole

Step 1: Preheat and Prep
Preheat your oven to 375°F (190°C). Lightly grease your baking dish with olive or avocado oil.

Step 2: Cook the Sausage
In a large skillet, cook the sausage over medium heat until browned and cooked through. Drain off any excess fat and set aside.

Step 3: Sauté the Vegetables
In the same skillet, add the onion and bell pepper. Cook until softened, about 5 minutes. Add the spinach and cook just until wilted.

Step 4: Mix the Eggs
In a large mixing bowl, whisk together the eggs, garlic powder, paprika, salt, and pepper.

Step 5: Assemble the Casserole
Spread the shredded potatoes evenly across the bottom of your baking dish. Top with the cooked sausage and vegetables. Pour the egg mixture evenly over the top, making sure everything is well-distributed.

Step 6: Bake and Serve
Bake for 35–40 minutes until the eggs are set and the top is lightly golden. Let cool for 5–10 minutes before slicing.

Tips for the Best Whole30 Quiche With Hash Browns

• Use dry shredded potatoes: Squeeze out excess moisture before layering to keep the casserole crisp.
• Don’t skip the veggies: They add flavor, texture, and nutrients.
• Let it rest: Allow the casserole to cool slightly for cleaner slices.
• Double it for meal prep: It freezes beautifully and reheats quickly.

Common Mistakes to Avoid in a Whole30 Breakfast Frittata

• Overcooking the eggs: They should be set but still tender.
• Skipping seasoning: Paleo doesn’t mean bland—season generously.
• Forgetting to grease the dish: This step ensures easy serving and cleanup.
• Using pre-shredded potatoes without checking ingredients: Many have preservatives or added sugars—always choose clean, Whole30-compliant ones.
