Ingredients

Gather these simple ingredients to create a truly unforgettable sausage casserole. Each component plays a crucial role in delivering a balanced, flavorful, and satisfying dish.

1 tbsp olive oil
(A good quality olive oil enhances the initial sauté of your vegetables and sausage.)
1 red bell pepper, diced (For a pop of color and a touch of sweetness. Yellow or orange bell peppers work just as well.)
1 lb Italian sausage
(Choose mild, medium, or hot Italian sausage based on your preference. Remove casings if using links.)
5 oz softened cream cheese, cubed (Crucial for achieving that rich, creamy texture. Ensure it’s softened to blend smoothly.)
6 cups frozen cauliflower rice
(No need to thaw! It cooks perfectly in the casserole, absorbing all the delicious flavors.)
½ tbsp Italian seasoning
(A classic blend that complements the Italian sausage beautifully.)
1 ½ cups shredded sharp cheddar cheese
(Divided: ½ cup for the mixture, 1 cup for topping. Freshly shredded cheese melts better than pre-shredded.)

Ingredient Spotlight & Substitutions:

This recipe is highly adaptable! Feel free to experiment with different ingredients to suit your taste or what you have on hand:

Sausage: While Italian sausage is recommended for its distinct flavor, you could use ground pork, ground turkey, or even spicy chorizo for a different kick. Just remember to adjust seasonings accordingly.
Vegetables: Beyond bell peppers, consider adding sliced mushrooms, chopped spinach (stirred in at the end with the cream cheese), diced zucchini, or even a handful of frozen peas for extra nutrients and color.
Cheese: Monterey Jack, mozzarella, or a Colby Jack blend would also be fantastic melted into this casserole. For a sharper flavor, grate some Parmesan cheese over the top.
Seasoning: If you don’t have Italian seasoning, a blend of dried oregano, basil, thyme, and a pinch of red pepper flakes will work wonders.

Instructions

Follow these simple steps for a seamless cooking experience and a perfectly baked casserole every time. Attention to detail will ensure every bite is bursting with flavor.

Prepare the Oven: Preheat your oven to 375°F (190°C). This ensures the oven is at the correct temperature for even cooking once your casserole is ready to go in.
Cook Sausage & Peppers: Heat the olive oil in a large skillet over medium heat. Once shimmering, add the diced red bell pepper and sauté for about 2 minutes until it begins to soften. Next, add the Italian sausage, breaking it up with a spoon as it cooks. Continue to cook until the sausage is thoroughly browned and no pink remains. This step is crucial for developing the foundational flavors of your casserole. Drain off any excess grease from the skillet to prevent the casserole from becoming oily. Remove the skillet from the heat, then add the cubed softened cream cheese. Stir vigorously until the cream cheese has completely melted and is smoothly incorporated with the sausage and peppers, creating a rich, creamy base.
Combine Ingredients: In a spacious medium-sized bowl, combine the cooked sausage and cream cheese mixture, the frozen cauliflower rice, ½ tablespoon of Italian seasoning, and ½ cup of the shredded sharp cheddar cheese. Stir all the ingredients together thoroughly until everything is well combined and the cauliflower rice is evenly coated with the creamy sausage mixture.
Bake the Casserole: Lightly grease a 9×13 inch baking dish. Pour the entire casserole mixture into the prepared dish, spreading it out evenly. Top generously with the remaining 1 cup of shredded cheddar cheese. Cover the baking dish tightly with aluminum foil. Bake in the preheated oven for 25 minutes. After 25 minutes, carefully remove the foil and bake for an additional 12 minutes, uncovered, or until the cheese on top is bubbly and beautifully golden brown. This final uncovered baking time helps to achieve that perfect crispy cheese topping. Remove from oven and let it stand for a few minutes before serving. Enjoy your hearty and flavorful casserole!

Tips for Success:

Softened Cream Cheese: For the smoothest cream cheese mixture, ensure it’s at room temperature before adding it to the hot skillet. This prevents lumps and ensures it melts evenly.
Don’t Thaw Cauliflower Rice: Using frozen cauliflower rice directly from the freezer is perfectly fine. It will cook and soften as the casserole bakes, absorbing all the delicious flavors.
Drain Excess Grease: Italian sausage can release a lot of fat. Draining it is essential for a less greasy and more enjoyable casserole.
Adjust Seasoning: Taste the sausage mixture before adding it to the casserole dish. Adjust salt, pepper, or Italian seasoning to your liking.
Golden Brown Top: For an extra golden and crispy cheese topping, you can turn on the broiler for the last minute or two of baking, but watch it very carefully to prevent burning.
