Instant Pot Recipe for Sausage and Peppers: One-Pot Italian Comfort

This one-pot wonder delivers classic Italian flavor with minimal effort. The Instant Pot transforms sausage and peppers into a tender, deeply savory dish that tastes like it simmered all day.

By pressure cooking everything together, the sausage releases its juices while the peppers and onions soften into a rich, flavorful base. It’s a foolproof method for achieving restaurant-quality results at home.

You’ll end up with perfectly cooked sausage, sweet and tangy peppers, and a sauce that’s ready to serve over pasta, rice, or crusty bread. The best part? Only one pot to clean.

Ideal for busy weeknights or lazy weekends when you crave comfort without the fuss.

Ingredients for Instant Pot Recipe for Sausage and Peppers

Nothing exotic here—just bold Italian flavors in one pot. Probably have most already.

The sausage is the backbone. Mild Italian from a good butcher shop hits different, but Johnsonville or Trader Joe’s works in a pinch. Look for casings that aren’t too tight—that means they’ll split less when cooking. Peppers? Pick whatever’s brightest and firmest at the store (avoid the soft, wrinkly ones). I usually grab a mix of colors for that classic look.

No white wine? Extra chicken broth with a splash of vinegar gets you 90% there. Don’t have fresh garlic? One-third the amount of garlic powder works, but fresh is better for that punch. Spicy sausage lovers can add an extra pinch of red pepper flakes. The canned tomatoes can be fresh if you’re feeling fancy (just chop and cook down a bit first).

Leftovers taste even better the next day—store in the fridge for up to 4 days or freeze for 3 months. Reheats like a dream. I like to prep the veggies the night before (keep them separate) so dinner’s on the table in 30 minutes flat.

Step-by-Step Instructions for Sausage and Peppers

This one-pot method locks in all the flavor while keeping cleanup a breeze.

Step 1: Sauté the Vegetables and Sausage

Set your Instant Pot to the Sauté function and add the 2 tbsp olive oil. Once hot, add the sliced yellow onion and cook for 3 minutes until it starts to soften and turn translucent.

Add the sliced 3 whole bell peppers and continue cooking for another 3-4 minutes until they begin to soften. Push the vegetables to the sides of the pot and add the 1.5 lb Italian sausage, breaking it into chunks as it browns. Cook until the sausage is no longer pink, about 5 minutes.

Step 2: Deglaze and Add Aromatics

Pour in the 0.25 cup white wine to deglaze the pot, scraping up any browned bits from the bottom with a wooden spoon. This step ensures all that flavor gets incorporated into the dish.

Stir in the minced 4 cloves garlic cloves, 1 tsp dried oregano, 1 tsp dried basil, 0.5 tsp red pepper flakes, 1 tsp salt, and 0.5 tsp black pepper. Cook for 30 seconds until the garlic becomes fragrant—don’t let it burn.

Step 3: Add Remaining Ingredients and Pressure Cook

Stir in the 1 can canned diced tomatoes (with juices), 2 tbsp tomato paste, and 0.5 cup chicken broth. Give everything a good stir to combine all the flavors.

Secure the lid on your Instant Pot, set the valve to Sealing, and cook on High Pressure for 5 minutes. The pot will take about 10 minutes to come to pressure before the cooking time begins.

Step 4: Release Pressure and Serve

Once the cooking time is complete, carefully switch the valve to Venting for a quick release. Remove the lid once the pressure has fully released—you’ll hear the float valve drop.

Give everything a final stir. The peppers should be tender, and the sausage should be fully cooked through. Taste and adjust seasoning if needed. Serve hot over pasta, rice, or with crusty bread to soak up all the delicious sauce.

Storing and Reheating This instant pot recipe for sausage and peppers

Refrigerator Storage

Let this dish cool for no more than 2 hours before transferring to airtight containers. I use glass containers with snap-tight lids. Store at 40°F or below for up to 4 days. The flavors deepen overnight as the herbs meld together. ❄️

Freezer Storage

This freezes beautifully for up to 3 months without texture changes. Portion into freezer bags, squeeze out excess air, and label with the date. I recommend quart-size bags for single meals.

Stovetop Reheating

My preferred method: transfer to a saucepan, add 2 tbsp chicken broth, and warm over medium-low heat for 8-10 minutes. Stir occasionally to prevent sticking. The sauce will thicken slightly as it reheats.

Microwave Reheating

Place individual portions in a microwave-safe bowl, cover with a damp paper towel, and heat on 70% power for 2-3 minutes. Stir halfway through. Add a splash of water if it looks dry.

Oven Reheating

For larger portions, spread in a baking dish, cover with foil, and warm at 350°F for 15-20 minutes. This method works perfectly when reheating the full batch for a crowd. 🔥
