How to Make Crockpot Sausage Casserole
Step 1: Brown the Sausages
Start by heating a tablespoon of olive oil in a large skillet over medium heat. Add your sliced sausages and let them cook for 3 to 4 minutes, turning occasionally, until they’re golden brown and just crispy at the edges. This extra step infuses your Crockpot Sausage Casserole with loads of flavor—don’t skip it! Once browned, move the sausage pieces straight into your slow cooker.
Step 2: Sauté the Vegetables
In the same skillet, toss in your chopped onion, minced garlic, sliced carrots, celery, and red bell pepper. Sauté them gently for about 5 minutes—just until they start to soften and their natural sweetness begins to shine through. Take a deep breath and enjoy the delicious smell at this stage! Once ready, transfer the veggies into the crockpot on top of the sausages.
Step 3: Add Everything to the Crockpot
Now it’s time to build the sauce that ties everything together. Pour in your diced tomatoes, tomato paste, chicken broth, and add the drained cannellini beans. Sprinkle over the smoked paprika, thyme, oregano, and a good pinch each of salt and pepper. Give everything a gentle stir—this helps the flavors start mingling even before the crockpot does its magic.
Step 4: Slow Cook to Perfection
Cover your crockpot and let it work its slow-cooking wonder. Set to low for 6 to 7 hours (or high for 3 to 4 hours if you need it sooner). As time ticks by, the sausages will soak up all the tangy, smoky sauce and the vegetables will become perfectly tender. If you want your Crockpot Sausage Casserole extra thick, just remove the lid for the last 30 minutes of cooking.
Step 5: Taste, Adjust, and Garnish
When the cooking time is up, give everything a final taste—add more salt or pepper if you like. Just before serving, sprinkle generous pinches of chopped fresh parsley over the top. That fresh green lift makes it all look and taste like a true homemade classic.
How to Serve Crockpot Sausage Casserole

Garnishes
Fresh chopped parsley is a must—its vibrant color and herbal zing make each bowl pop. If you want to get a bit fancy, add a few shavings of Parmesan or even a drizzle of good olive oil just before serving. These extra touches transform Crockpot Sausage Casserole into something truly restaurant-worthy right at home.
Side Dishes
You can never go wrong with a hunk of warm, crusty bread to mop up all the delicious sauce. Alternatively, try serving your Crockpot Sausage Casserole over a bed of creamy mashed potatoes, or spoon it onto steamed rice for a heartier, more filling meal. If you’re looking for something lighter, offer a simple green salad on the side for freshness and crunch.
Creative Ways to Present
For gatherings or casual family dinners, ladle the casserole into small oven-safe dishes, top with breadcrumbs and a little cheese, then flash under the broiler for a bubbly, golden crust. Or, pile it onto baked sweet potatoes for a rustic, colorful twist. However you present it, everyone will love the comforting flavors baked into every spoonful of Crockpot Sausage Casserole.
Make Ahead and Storage
Storing Leftovers
Once your Crockpot Sausage Casserole has cooled, simply transfer leftovers into airtight containers. It will keep happily in the fridge for up to 4 days, making it perfect for make-ahead lunches and stress-free weeknight dinners. The flavors often deepen after a night or two, so second-day servings can be even better!
Freezing
This casserole freezes beautifully. Spoon cooled portions into freezer-safe containers or sturdy resealable bags (for space-saving), label with the date, and freeze for up to 3 months. Make sure to let it thaw overnight in the fridge before reheating so everything heats evenly.
Reheating
Gently reheat the casserole in a saucepan on the stovetop over medium-low heat, adding a splash of broth or water if it’s a little thick. You can also microwave individual portions, covered, stirring halfway through. If you froze your Crockpot Sausage Casserole, let it thaw in the fridge, then reheat as above for best results.
