Sausage and Peppers in a Crock Pot

This is my favorite go-to recipe on our food blog. Seriously! Not only is it just a handful of simple ingredients, but there’s also just something amazing and special about this combination of flavors. I’m sure it has something to do with that flavorful Italian sausage grease mixed with sauce 😉

Seriously though, if you’re on the hunt for crockpot Italian sausage recipes, it doesn’t get better than this. I could honestly eat this every week!

This is a crockpot sausage and peppers recipe with sauce, you’ll find some recipes out there I’m sure that don’t add sauce at all, or use crushed tomatoes or tomato sauce instead of pasta sauce. We are huge sausage fans at our house and eat them regularly, and I’ll tell ya what, not using a delicious marinara sauce for this recipe I’m sure would still be good, but it will NOT turn out as great.

Ingredient Notes

The ingredients for crockpot sausage and peppers is super simple! We love to keep extra frozen Italian sausages and frozen sliced peppers in the freezer to know we already have ingredients on hand when we need a quick meal.

• Italian sausages – you can use either pork or chicken, most brands come 5 to a pack, some come as a pack of 4.
• red & green peppers – while using a variety of colored peppers is pretty, it’s perfectly fine to use one color. Green, red, yellow, or orange are all great options
• onion – red is pretty, but any variety will work like yellow or sweet onions.
• seasoning- garlic salt, Italian seasoning, black pepper
• chunky marinara sauce – Rao’s makes the best store bought marinara on the market, it tastes just like homemade, plus it has no added sugar or artificial ingredients. While Amazon and many grocery stores now carry it, Walmart sells it for 25% less than most places.
• olive oil – for searing the sausage in, any high heat oil will work
• Mozzarella cheese– (optional)  any white cheese or cheese blend will work like Monterey Jack, 3 cheese blend, or Monterey Jack
• buns – (optional) serve the recipe casserole style over polenta, pasta, zoodles, or cauliflower rice, OR serve them like a hot dog on a bun.

Optional

• shredded cheese (mozzarella, Italian, Monterey Jack, or Colby Jack)
• stadium-style buns

Step by Step Instructions

This recipe comes together in 10 minutes and then slow cooks during the day while you’re gone. We’ve also made instant pot sausage and peppers if you want them quickly and have an Instant Pot.

To summarize the Italian sausages and pepper recipe process, you’ll be browning the sausages and then cooking the sausages, peppers, and onions in a large skillet over medium heat with a seasoned sauce before you cover and cook them for 15 minutes until heated through.

Sear the Sausage

Heat a  skillet on medium heat and add a drizzle of olive oil to the pan.

Sear the Italian sausages 2-3 mins on each side until starting to brown. You aren’t trying to cook them all the way through, you’re just browning the outside a bit which always increases the flavor while slow cooking.

Assemble

Lay the seared Italian sausages in the bottom of a crock-pot.

Add the uncooked sliced onions and peppers on top of the sausages.

Sprinkle the garlic salt, black pepper, and Italian seasoning over the top.

Spread the marinara sauce over the onion and pepper mixture.

Slow Cook

Cook the crock pot sausage and peppers recipe on high for 3-4 hours or low for 6-7 hours until the peppers are soft and the Italian sausage is cook through. Add more salt and pepper to taste if desired. The sausages are cooked through when the internal temperature is at least 160 degrees, but sausages often do well up to 190 degrees and still stay juicy inside.

The recipe is seriously SO delicious as is, but to take it up a notch, take the sausage and peppers out of the slow cooker and spread into a broiler-safe pan with the sausages on the top.

Add Cheese

Adding cheese is an optional step, but highly recommended!

Sprinkle with your favorite shredded white cheese, I think mozzarella, Monterey Jack, an Italian blend, or Colby Jack would all be great choices. We used mozzarella since that’s what we had in the fridge at the time we made up the slow cooker sausage and peppers recipe.

We used about 1/2-3/4 cup of shredded cheese for 5 peppers.

Broil the Italian sausage and peppers mix for 1-2 minutes 4″ from the heat source until the cheese is melted.

Recipe Tips

• Skip browning the Italian sausage before adding it to the crockpot to make the dish even faster
• Using chicken sausage instead of pork lightens up the recipe
• The recipe uses just one package of Italian sausages, you can definitely double this recipe to serve a crowd or just to have leftovers
• This makes a great freezer meal too. Freeze the recipe before adding the cheese for best results, and then add the cheese after it’s done cooking.
• Many people also love to eat sausage and peppers in a crockpot served on a bun like a big messy hot dog, which is so tasty too! I’d recommend toasted the buns slightly before serving, if you want the crockpot sausage, peppers and onions with BOTH cheese and a bun, you’ll want to:
  • toast the bun and add a little butter to each
  • add the crock pot sausage and peppers mix
  • sprinkle with shredded cheese
  • broil the sausage and peppers in the bun until the cheese is melted, keeping an eye on things so the buns don’t burn.
  • Serve and enjoy!

Common Questions

What Side Dishes Go with Sausage and Peppers?

Keto Sausage and Peppers?

If you’re following a low carb or keto diet you might be wondering if sausage and peppers are keto. My husband is currently on a keto diet and this is actually one of his favorite recipes!

As long as you’re using a keto-friendly marinara sauce like Rao’s and don’t serve the keto sausage and peppers on a bun, this is a keto-friendly recipe.

Each serving of keto sausage and peppers is 6 net carbs without the bun and with a sugar-free sauce like Rao’s. We highly recommend you calculate this yourself also since calculators can vary as can brands of ingredients.
