When I need a dinner that feels hearty and comforting without asking much from me after a long workday, this 5-ingredient slow cooker beef sausage recipe is exactly the kind of meal I reach for. Using a raw fresh beef sausage rope keeps things simple while still giving you rich, savory flavor, and the slow cooker does all the heavy lifting. It is the kind of practical Midwest-style dinner that turns a few budget-friendly ingredients into something that tastes like you put in a whole lot more effort than you actually did.

This dish is especially good with buttery mashed potatoes, egg noodles, or fluffy rice to soak up the rich tomato-onion sauce. I also like serving it with green beans, a simple side salad, or roasted carrots to round things out. If you want to lean into comfort-food mode, a piece of warm crusty bread on the side makes it even better.

Ingredients

1 raw fresh beef sausage rope, about 1 1/2 to 2 pounds

1 large yellow onion, sliced
1 jar (24 ounces) marinara sauce
1 green bell pepper, sliced
1 teaspoon Italian seasoning

Directions

1. Lightly coat the inside of your slow cooker with nonstick spray if desired, then place the raw fresh beef sausage rope in the bottom.

2. Scatter the sliced onion and green bell pepper over and around the sausage.

3. Pour the marinara sauce over the top and sprinkle with the Italian seasoning.

4. Cover and cook on low for 5 to 6 hours or on high for 3 to 4 hours, until the sausage is fully cooked and the vegetables are tender.

5. Transfer the sausage to a cutting board, slice into serving pieces, then return the pieces to the slow cooker and spoon the sauce over the top before serving.

Variations & Tips

Make it heartier: Serve the sausage and sauce over pasta, polenta, rice, or mashed potatoes to stretch the meal and make it extra filling for bigger appetites.

Add more vegetables: If you have a little more room in the slow cooker, mushrooms or red bell pepper work really well here and blend right into the sauce.

Brown for deeper flavor: If you have a few extra minutes, you can brown the sausage rope in a skillet before adding it to the slow cooker. It is not required, but it adds a richer, deeper flavor.

Meal prep tip: Slice the onion and pepper the night before so in the morning you can just layer everything into the slow cooker and get on with your day.

Check doneness: Because sausage thickness can vary, make sure the beef sausage is cooked through before serving. If needed, give it a little extra time until it is fully done and easy to slice.
