The Full Keto Italian Sausage Bake Recipe
Ingredients
- 10 Italian Sausages (hot or mild)
- ½ cup water
- 24 oz (680g) Low Carb Marinara Sauce (no added sugar)
- 1 ½ cups (170g) shredded mozzarella cheese
- ¼ cup (25g) grated Parmesan cheese
- ¼ tsp Italian seasoning
- ¼ tsp garlic powder
- ½ tsp basil seasoning
- ⅛ tsp black pepper
Instructions
- Begin by slicing the Italian sausages into bite-sized pieces. In a skillet over medium heat, brown the sausage slices on both sides for about 5-7 minutes. Tip: Make sure to not overcrowd the skillet to ensure even browning.
- Once browned, add ½ cup of water to the skillet. Cover with a lid and let it simmer on low heat for 8 minutes. Tip: This helps keep the sausages juicy and flavorful.
- Preheat your oven to 375°F (190°C). While the oven is heating, grease a 9 x 13-inch casserole dish to prevent sticking.
- Transfer the cooked sausages into the greased casserole dish. Pour the marinara sauce evenly over the sausages.
- Sprinkle the shredded mozzarella cheese and grated Parmesan cheese generously on top of the sauce and sausages.
- Add the Italian seasoning, garlic powder, basil seasoning, and black pepper over the cheese layer for an extra flavor boost.
- Bake in the preheated oven for 18 minutes. For an extra bubbly and browned cheese topping, move the dish to the top rack for the last 2 minutes. If desired, you can turn the oven to broil for the final minute, but keep a close eye on it to prevent burning.
- Once done, allow the casserole to cool slightly before serving to let the flavors meld together.
Serving Suggestions and Variations for Keto Italian Sausage Bake
