These slow cooker Italian sausage marinara sliders are a stress-free feeding solution for busy holiday weeks, game days, and casual family dinners.

Ingredients
- 2 lb sweet Italian sausage links
- 1 medium yellow onion, sliced
- 1 red bell pepper, sliced
- 1 green bell pepper, sliced
- 3 cloves garlic, minced
- 24 oz marinara sauce
- 1 tbsp Italian seasoning
- 1/2 tsp crushed red pepper flakes
- 12 slider rolls, split and toasted
- 6 slices provolone cheese, halved
- 2 tbsp fresh basil, chopped for garnish
Instructions
- Place the sliced yellow onion, red bell pepper, green bell pepper, and minced garlic into the bottom of a 6-quart crockpot.
- Arrange the raw Italian sausage links over the vegetables in an even layer.
- Pour the marinara sauce evenly over the sausages and sprinkle with Italian seasoning and crushed red pepper flakes.
- Cover and cook on LOW for 4 to 5 hours (or HIGH for 2 to 3 hours) until the sausage reaches an internal temperature of 160 F.
- Remove the sausage links, slice into thick coin pieces or bite-sized chunks, and return them to the crockpot sauce to coat thoroughly.
- Spoon the warm sausage and marinara mixture onto toasted slider rolls, top each bottom bun with half a slice of provolone cheese, close the rolls, and sprinkle with fresh chopped basil before serving.
Tips
- For extra bubbly melted cheese, place assembled slider bottoms with cheese under the oven broiler for 1 to 2 minutes before capping with top buns.
- Store leftovers in an airtight container in the refrigerator for up to 4 days; reheat sauce and sausage gently on the stovetop or microwave before assembling fresh sliders.
- You can swap sweet Italian sausage for spicy Italian sausage if your family prefers extra heat.
