Ingredients

Scale

Protein and Eggs

1 pound Whole30 approved breakfast sausage (or turkey sausage if not Whole30)
12 large eggs

Vegetables

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)

Seasonings and Oils

Olive oil for pan
1/2 tsp garlic powder
1 tsp salt-free Mrs. Dash Onion & Herb Seasoning + extra for sprinkling on casserole
Salt and pepper, to taste
Hot sauce (optional, to taste)

Instructions

Preheat the oven: Preheat your oven to 350 degrees Fahrenheit to prepare for baking the casserole.
Prepare the vegetables: Dice the green and red bell peppers and the onion. Chop the spinach if using fresh. Set all the vegetables aside.
Whisk the eggs: Crack 12 large eggs into a medium bowl and whisk thoroughly until fully combined. Add a few drops of hot sauce if desired, and whisk again to incorporate.
Cook the sausage: Heat a large skillet over medium-high heat and add a small amount of olive oil to coat the pan. Add the sausage and cook until fully browned and cooked through. Drain any excess grease and set the sausage aside.
Sauté the vegetables: Using the same skillet, cook the diced peppers and onions over medium heat for about 2 minutes until slightly softened. Add the chopped spinach and cook for an additional minute. Remove the skillet from the heat.
Combine sausage and veggies: Return the cooked sausage to the skillet with the vegetables. Add garlic powder, 1 teaspoon of Mrs. Dash Onion & Herb Seasoning, salt, and pepper. Stir everything together until well mixed.
Transfer to baking dish: Pour the sausage and vegetable mixture into a 9×13 inch glass baking dish that has been lightly sprayed with non-stick olive oil.
Add the egg mixture: Pour the whisked eggs evenly over the sausage and vegetable layer. Sprinkle additional Mrs. Dash Onion & Herb Seasoning on top to add flavor.
Bake the casserole: Place the dish in the preheated oven and bake for 25-30 minutes, or until a knife inserted into the center comes out clean and the eggs are fully set.
Cool and serve: Allow the casserole to cool for 5-10 minutes before slicing. Optionally, top each serving with salsa or your preferred condiments and enjoy your flavorful Whole30 breakfast casserole.

Notes

You can substitute the sausage with turkey sausage if you are not following Whole30 strictly.
Fresh spinach adds texture, but frozen spinach works fine if thawed and drained well.
Feel free to adjust the seasoning levels to your taste, especially with salt and hot sauce.
This casserole can be made ahead and refrigerated to reheat for quick breakfasts throughout the week.
Use a non-stick spray that is Whole30 compliant to avoid sticking and ease cleanup.
