Sausages: Use your favorite sausages. I use pork sausages, but you can substitute these for chicken sausages for a low fat and low calorie version.
Canned diced tomatoes: This is the base of our sauce. You can use tomato sauce, or even jarred pasta sauce as a substitute.
Butter beans: Also known as large white beans. These add flavor, protein and texture to the casserole. You can substitute these with a can of baked beans, cannellini beans, or any other beans of your choice.
Carrots, celery, pepper, leek: Vegetables add to the flavor, and make the dish a little healthier. As they are slow cooked, the vegetables are almost mashed into the sauce, making it easy to eat extra veg without really realizing.
Onion + garlic cloves: Add to the flavor and texture of the dish.
- Brown the sausages: Add vegetable oil to a skillet or frying pan, and sear the sausages for a few minutes on each side, until they have gently browned. Transfer them to the slow cooker.
- Saute the vegetables: Add finely diced onion, grated garlic, and diced carrots, celery, leek and red pepper to the skillet. Saute for a few minutes until the onion is soft. Transfer the vegetables to the slow cooker.
- Slow cook the sausage casserole: Add the canned diced tomatoes, Worcestershire sauce, thyme, oregano, paprika, salt and pepper to the slow cooker. Cook on HIGH for 3 hours, or on LOW for 6 hours.
- Add the beans: Drain and rinse the butter beans, and add them to the slow cooker. Slow cook for another 15 minutes.
- Serve: Serve the sausage casserole with your favorite side dishes.
- If you're short on time, you can skip the steps of sautéing the sausages and vegetables. These steps add a lot of flavor to the stew, but are not strictly essential.
- Avoid removing the lid of the slow cooker as the sausage stew cooks, as this would allow a lot of heat to escape, and increase the required cooking time.
Sausage casserole can be served alone, but many prefer to enjoy it with a side dish. Here are some of my favorite recipes to pair it with:
- Healthy Mashed Potatoes - Sausage casserole and mashed potatoes are the perfect pairing.
- Air Fryer Baked Potato - These baked potatoes are a fantastic alternative to mash.
- Dill Rice - This simple, but flavorful rice recipe pair really nicely with the flavors of the casserole.
- Bread - Serve the sausage casserole with garlic bread, toasted bread, or a slice of sourdough for a more filling meal.
Vegetarian sausage casserole: You can easily make this stew vegetarian by using vegan or meat free sausages.
Extra vegetables: Feel free to add any other vegetables, such as sweet potatoes, mushrooms, peas, kale, spinach, zucchini or corn. Add hard vegetables along with the vegetables in the recipe, or add soft vegetables such as leafy greens and peas along with the beans.
Keto + low carb: Omit the beans, and replace the carrots with more peppers for a low carb version. Make sure to also use keto friendly sausages.
