Tips for the Best Slow Cooker Sausage and Peppers
Brown the Sausage First
Browning isn’t required, but it gives the sausage a deeper, richer flavor.
Choose Colorful Peppers
Red and yellow peppers provide natural sweetness, while green peppers add a slightly more savory flavor.
Using several colors also makes the dish look beautiful.
Don’t Overcook the Peppers
If you prefer peppers with some texture, avoid cooking the dish much longer than necessary.
Use a Good Tomato Sauce
Since the tomato sauce forms much of the base, choose a variety you enjoy.
Adjust the Spice
Use mild sausage and no red pepper flakes for a milder meal.
For more heat, add spicy sausage or crushed red pepper.
Can I Use Italian Sausage?
Yes.
Italian beef sausage or pork sausage can both work well.
Choose mild or spicy sausage depending on your preference.
Can I Use Pre-Cooked Sausage?
Absolutely.
Pre-cooked sausage is convenient and works especially well for this recipe.
Because it’s already cooked, you’re mainly heating it and allowing the flavors to combine.
Can I Use Ground Beef Instead?
Yes, but the texture will be different.
Brown the ground beef first and drain any excess grease before adding it to the slow cooker.
Can I Add Mushrooms?
Definitely.
Sliced mushrooms pair beautifully with sausage, peppers, and tomato sauce.
Can I Add Potatoes?
Yes.
Add small chunks of firm potatoes at the beginning of cooking.
Make sure they’re tender before serving.
Can I Add Cheese?
Absolutely.
Mozzarella or Parmesan makes a delicious finishing touch.
Sprinkle cheese over the sausage and peppers just before serving.
