Ingredients For Crock Pot Italian Sausage Peppers And Onions

• 5-6large Italian sausage links – you can use sweet Italian sausage, spicy Italian sausage or your favorite fresh link sausage
• 24ouncesmarinara sauce – or your favorite jarred tomato based sauce. I would suggest using a sauce that doesn’t have meat in it as we’ll have a lot of meat already from the sausage
• ½teaspoonoregano
• ½teaspoongarlic powder
• ½teaspoonsalt
• ¼teaspoonpepper
• 3bell peppers – sliced between ¼ and a half inch stripsuse a mix of red, yellow and orange. You can also use green bell peppers if you prefer, my family just prefers the other colors.
• 1white onion– sliced between ¼ and a half inch strips, you can also use a yellow onion, purple onion or my family’s favorite, a sweet onion

Depending on how flavorful the marinara sauce or red sauce I have is, I’ll sometimes throw in 1/2 a teaspoon if Italian seasoning also for a bit more flavor.

If your family likes things spicy and you have regular Italian sausage you can add a little cracked red pepper flakes. I usually start with 1/4 teaspoon of cracked red pepper flakes because my daughter prefers recipes not be super spicy. Then if we want it spicer, we each add more cracked red pepper flakes at the table to our own tastes.

How To Make Crock Pot Italian Sausage Peppers And Onions

1. Spray a skillet with a little oil and place over medium high heat. Brown the sausages for about 2-3 minutes on each side just until they begin to get a little color. The sausages won’t be cooked through.

2. Spray the slow cooker with oil then add the marinara to the bottom of the slow cooker. Pour ¼ cup of water to the tomato jar and shake it with the lid on to get all of the tomato into the slow cooker.

3. Add oregano, garlic powder, salt and pepper to the sauce. Mix the spices into the sauce with a spoon or spatula.
4. Place the bell pepper slices and sliced onions on top of the tomato sauce. Add the sausages on top of the peppers and onions. Push the sausages down a little into the peppers and onions.

5. Set the slow cooker to cook for 5-6 hours on low or 3-4 hours on high. The sausages should be at least 160 degrees when measured with a meat thermometer. Flip to the warm setting until you are ready to serve, then enjoy on rolls.

Variation Idea Try With Italian Sausage Dish With Meatballs

My Italian grandma used to simmer homemade meatballs with the sausage and it gives everything a lot of flavor. We used to have a big platter of meatballs and sausages that we would pass around along with a big bowl of ziti pasta (her favorite). I recommend browning the meatballs in a pan first before tossing them in the slow cooker with the Italian sausage.

Or if you have extra ground pork, try these ground pork lettuce wraps as an appetizer or dinner!

Can I Prep This Italian Sausage And Peppers Recipe Ahead Of Time?

Yes you can totally prep this dish up to 24 hours in advance. I like to prep everything, pop it in the fridge, and then pour the sauce over the sausage and peppers right before I start the slow cooker.

The slow cooker can switch to warm with a timer and sit for a while if you’re not ready to eat when the recipe is finished cooking. My favorite slow cooker is programmable with a warm setting.

Will Slow Cooker Sausage And Peppers Freeze?

Yes, leftovers of this sausage peppers and onions recipe freeze beautifully! Store any leftovers in an airtight freezer container or freezer zip-top bag.

You can then add it to a little bit of red sauce and reheat on the stove until just cooked through. This reheats pretty quickly in about 15 minutes or so, and can then be made into sandwiches or added to pasta.

What Size Slow Cooker Is Needed For This Recipe?

I used a 6 quart slow cooker for this recipe. You could likely use a 4 quart slow cooker or an 8 quart slow cooker for this recipe also.

Can You Double Or Triple This Recipe?

You could double the sausage in this recipe, but I would eyeball the amount of pepper and onions a little bit if you are using a 6 quart slow cooker. It will depend on how big the pepper is, you may just have to either reduce the vegetables or use a larger slow cooker. The peppers and onions will cook down a lot, but fitting it all in the slow cooker when raw may get tricky when you double or triple the recipe.

If you need more peppers and onions extra could be sauteed in a pan on top of the stove to ensure you can put more of the meat in the crock pot.

How Long Will Crock Pot Sausage And Peppers Last?

Expect that sausage, peppers and onions will last fro about three days. Store leftover sausage, peppers and onions in a covered airtight container in the refrigerator.
