What You’ll Need
1 pound Whole30 approved breakfast sausage or turkey sausage if not Whole30
Olive oil for pan
1 white or yellow onion, diced
1 green bell pepper, diced
1 red bell pepper, diced
2 cups fresh spinach, chopped (or 16 ounces frozen, thawed and drained)
1/2 tsp garlic powder
1 tsp salt-free Mrs. Dash Onion & Herb Seasoning + sprinkle on top of casserole
Salt and pepper, to taste
12 large eggs
Hot sauce (optional to taste)
For a healthier spin, consider swapping fresh spinach for kale or adding in some diced tomatoes for extra flavor!
Directions to Follow
- Preheat your oven to 350°F (175°C).
- Dice the onion, green bell pepper, and red bell pepper, and chop the spinach. Set these aside.
- In a medium bowl, crack the 12 eggs and whisk them well. If you like a bit of heat, add a few drops of hot sauce and mix until blended.
- Heat a drizzle of olive oil in a large skillet over medium-high heat. Cook the sausage until fully browned and cooked through. Drain any excess fat and set the sausage aside.
- In the same skillet, add the diced onion and bell peppers. Cook on medium heat for about 2 minutes until slightly softened. Add the chopped spinach and cook for an additional minute. Remove from heat.
- Return the cooked sausage to the skillet with the veggies and sprinkle in the garlic powder and Mrs. Dash seasoning. Stir until well combined.
- Transfer the sausage and vegetable mixture to a glass 9×13 baking dish that has been sprayed with non-stick olive oil.
- Pour the egg mixture over the sausage and veggies, making sure it spreads evenly. Sprinkle a bit more of the onion and herb seasoning on top.
- Bake for 25-30 minutes or until a knife inserted into the center comes out clean.
- Allow the casserole to cool for about 5-10 minutes before slicing and serving. Serve with salsa if desired.
Best Ways to Enjoy It
This breakfast casserole is a complete dish on its own, but you can easily pair it with a side of fresh fruit or avocado slices for a refreshing contrast. For those who enjoy a bit of zest, serving it with salsa or hot sauce can elevate the flavors even further. If you’re planning a brunch, consider adding a side of hash browns or crispy bacon to round out the meal.
How to Store
To keep your leftover casserole fresh, store it in an airtight container in the refrigerator. It will last up to 4 days. When you’re ready to enjoy it again, simply reheat slices in the oven at 350°F (175°C) for about 10-15 minutes or in the microwave for 1-2 minutes until warm. Be sure to check that it’s heated through before serving!
Helpful Cooking Tips
- Be sure to thoroughly cook the sausage for the best flavor and texture.
- If using frozen spinach, remember to thaw and drain it well to avoid excess moisture in the casserole.
- You can whisk in some unsweetened almond milk for creaminess if you want a richer egg mixture, keeping it in line with Whole30.

This casserole is versatile! You could easily swap out the sausage for diced ham or crumbled bacon. For a Mediterranean twist, try adding olives and feta cheese instead of the traditional seasoning.
