Why This Casserole is Best

Sausage and Peppers is an Italian American staple, especially in the midwest. Made with inexpensive ingredients, it’s the perfect way to feed a crowd.

• Made with with Hot Italian sausage for spicy flavor.
• High in protein, low in net carbs.
• Baked in a zesty tomato sauce.
• Topped with melted provolone.
• Delicious on its own or with cauliflower rice!

You usually find sausage, peppers and onions served on hoagie rolls or buns. This baked version has all the great flavor of those satisfying sandwiches, but without the gluten and extra carbs.

Ingredient Notes

• Hot Italian Sausage – Choose bulk sausage with no added sugars. If you can’t find bulk sausage, you can use links with the casings removed.
• Tomato sauce – You will need canned tomato sauce with no added flavorings or sugar for this casserole recipe. We’ve also made sausage and peppers with fresh pureed tomatoes but found the sauce turns out thinner.
• Green bell peppers are the traditional choice for sausage and peppers. Remove the seeds and dice them into small pieces.
• Provolone cheese – Sliced mozzarella or fontina cheese can also be used as the cheesy top layer for sausage and peppers casserole.

Easy Instructions

Oven instructions:

1. Start by browning the Italian sausage in a skillet. Drain, then return it to the skillet along with tomato sauce, and diced tomatoes.
2. Cook until ingredients are well combined, then transfer them to a casserole dish.
3. Add the peppers and onions to the skillet. Cook until softened. Add to the casserole dish and combine with the meat mixture.
4. Cover the dish with foil and bake for 30 minutes. Take off the foil and top the casserole with cheese slices. Increase the oven temperature and bake the casserole for another few minutes. The cheese should be melted, bubbly and slightly browned.

Slow cooker instructions:

• Brown the sausage in a skillet on the stove top. Add it to the slow cooker along with the remaining ingredients (except the cheese). Cover and cook sausage and peppers on low for 6-8 hours.
• If you want a bubbly cheese topping, you can transfer the sausage and peppers to a casserole dish, then add the cheese on top and place it under the broiler for a couple of minutes.
• You can also just add the cheese to the slow cooker at the end of cooking and let it melt a bit before serving. It will still taste great, although it won’t get brown and bubbly like the baked version.

Serving Suggestions

We love this Sausage and Peppers Casserole over a bed of riced cauliflower. It would also be perfect paired with cauliflower mash or a side of roasted radishes.
