Ingredients For Sausage Casserole Recipe
Sausages: Choose either pork or beef sausages based on your preference. They add a rich, meaty flavor to the dish.
Onion: A large chopped onion provides a sweet and savory base for the casserole.
Garlic: Minced garlic cloves enhance the overall flavor with a pungent, aromatic touch.
Chopped tomatoes: A can of chopped tomatoes adds a tangy and slightly sweet element to the sauce.
Chicken broth: This provides a savory depth to the sauce and helps to cook the vegetables.
Dried thyme: Adds a subtle earthy flavor that complements the other ingredients.
Dried oregano: Brings a slightly bitter, aromatic flavor that enhances the overall taste.
Baby potatoes: Halved baby potatoes become tender and flavorful as they cook in the casserole.
Carrots: Sliced carrots add a sweet and earthy flavor, as well as a bit of color to the dish.
Salt and pepper: Essential for seasoning and bringing out the flavors of the other ingredients.
Technique Tip for This Recipe
When browning the sausages, make sure to do so over medium heat to ensure they cook evenly and develop a rich, caramelized exterior. This step not only enhances the flavor but also helps to render some of the fat, which will add depth to the casserole. Additionally, when sautéing the onion and garlic, be patient and let them cook until they are soft and translucent. This will bring out their natural sweetness and create a more flavorful base for your tomato mixture.
