- Sausage (1 lb): Choose pork, chicken, or turkey sausage depending on your preference for a rich or lighter flavor.

- Potatoes (1 1/2 cups, diced): Yukon Gold or Russet potatoes add hearty texture and absorb the casserole’s savory liquids.
- Diced tomatoes (1 can, 14.5 oz, undrained): Bring moisture and a tangy richness to the dish.
- Chicken broth (1 cup): Infuses the casserole with warmth and depth, keeping everything juicy.
- Dried thyme (1 teaspoon): Adds an earthy, aromatic note that complements the sausage beautifully.
- Dried oregano (1 teaspoon): Offers a hint of Mediterranean flair.
- Paprika (1/2 teaspoon): Adds a subtle smoky warmth and color.

How to Make Slow Cooker Sausage Casserole Recipe
Step 1: Prepare the Sausage
If you are using whole sausages, slice them into approximately 1-inch pieces. This makes them easier to brown and ensures even cooking throughout your casserole.
Step 2: Brown the Sausage
In a skillet over medium heat, cook the sausage pieces until they turn a beautiful golden brown, which usually takes about 5-7 minutes. Use a spoon or spatula to break the sausage into smaller chunks as it cooks. This step enhances the flavor by caramelizing the sausage. If your sausage is pre-cooked, feel free to skip this part and just slice before adding to your slow cooker.
Step 3: Add Ingredients to Slow Cooker
Transfer the browned sausage or sliced uncooked sausage directly into your slow cooker. Then add the chopped onion, minced garlic, sliced carrots, diced potatoes, diced tomatoes with their juice, chicken broth, dried thyme, oregano, paprika, salt, and pepper. This is where all the flavors begin their slow mingling and melding, setting the stage for the perfect casserole.
Step 4: Start Cooking
Give everything a good stir to combine the ingredients well. Cover your slow cooker and set it on low for 6-8 hours or on high for 3-4 hours, depending on your schedule. The slow cooker will tenderize the vegetables and cook the sausage through, creating a rich and hearty base for your meal.
Step 5: Add Frozen Peas
About 30 minutes before serving time, stir the frozen peas into the slow cooker. This not only adds a pop of color but also gives the casserole a nice sweetness and fresh bite that balances the savory sausage and earthy root vegetables.
Step 6: Optional Cheese Topping
If you love a melty cheesy finish, sprinkle shredded cheddar or mozzarella on top about 10-15 minutes before serving. Cover the slow cooker again so the cheese has time to melt into a gooey, satisfying layer that brings everything together.
Step 7: Serve and Enjoy
Before serving, give the casserole a gentle stir to distribute the cheese (if using) and peas evenly. Then scoop out generous portions of this comforting Slow Cooker Sausage Casserole Recipe and watch your family or guests savor every bite.
How to Serve Slow Cooker Sausage Casserole Recipe
Garnishes
A sprinkle of fresh chopped parsley or chives brightens up this casserole visually and adds a fresh, herbal pop that complements the herbs inside the dish. For a touch of zest, a light drizzle of a good-quality olive oil or even a dash of hot sauce can elevate the flavors.
Side Dishes
This sausage casserole is hearty enough to be a meal on its own but pairs wonderfully with simple green salads, crusty bread for mopping up the sauce, or steamed greens like broccoli or spinach. These accompaniments provide balance and a refreshing contrast to the rich casserole.
Creative Ways to Present
For a cozy family dinner, serve it straight from the slow cooker to keep it warm and inviting. For a more festive occasion, plate individual servings in shallow bowls topped with a little cheese and fresh herbs or serve it alongside a side of mashed cauliflower for a low-carb twist. The versatility of this Slow Cooker Sausage Casserole Recipe means you can dress it up or down easily.
Make Ahead and Storage
Storing Leftovers
Place any leftover casserole in an airtight container and refrigerate it within two hours of cooking. It will stay fresh for up to 3 days, making it a perfect ready-to-go meal for busy weekdays.
Freezing
This casserole freezes exceptionally well. Let it cool completely, then transfer to a freezer-safe container or bag. It can be frozen for up to 2 months. Just remember to thaw it overnight in the refrigerator before reheating to keep the texture and flavors intact.
Reheating
Reheat the casserole gently on the stovetop over medium-low heat or in the microwave. Stir occasionally to warm it evenly. If it seems a bit thick, add a splash of chicken broth or water to loosen it up and keep it comforting and saucy.
FAQs
Can I use other types of sausage for this recipe?
Absolutely! This Slow Cooker Sausage Casserole Recipe works great with pork, chicken, turkey, or even vegetarian sausages. Just adjust cooking times slightly if you’re using pre-cooked options.
Do I have to brown the sausage before adding it to the slow cooker?
Browning the sausage adds excellent flavor and texture, but if you’re short on time, you can skip this step. The casserole will still be delicious, just a bit less caramelized.
Can I make this recipe in an Instant Pot instead of a slow cooker?
Yes, you can adapt the recipe for an Instant Pot using the sauté and slow cook functions or pressure cooking. Just be sure to adjust cooking times accordingly and follow your Instant Pot’s guidelines.

If you’re lactose intolerant, consider using lactose-free cheese or skip the cheese topping altogether. The casserole will still be rich and flavorful without it.
