What Ingredients You Will Need

This recipe uses simple, wholesome ingredients to deliver bold flavor and satisfying texture without the fuss. Most of these are pantry staples and fresh produce you can find year-round.

• Italian sausage links: about 1.5 pounds (680 grams), either mild or spicy depending on your heat preference (I usually go for Johnsonville for consistent flavor)
• Bell peppers: 3 large, mixed colors (red, green, yellow) sliced into strips (adds sweetness and bright color)
• Onion: 1 large yellow or white onion, thinly sliced (for sweetness and depth)
• Garlic cloves: 3 minced (brings aromatic warmth)
• Crushed tomatoes: 1 can (14.5 oz / 411 grams) or substitute with marinara sauce for extra herby flavor
• Olive oil: 1 tablespoon (helps soften veggies and adds richness)
• Dried oregano: 1 teaspoon (classic Italian herb note)
• Dried basil: 1 teaspoon (rounds out the herb profile)
• Red pepper flakes: 1/4 teaspoon (optional, for extra kick)
• Salt and black pepper: to taste (seasoning is key here)
• Sub rolls or hoagie buns: 6, preferably crusty and sturdy to hold all that goodness (I like Amoroso’s rolls for authenticity)
• Provolone cheese slices: 6 (optional, but adds melty, mild flavor that pairs beautifully)

Substitution tip: If you prefer a gluten-free option, swap the rolls for gluten-free buns. For a dairy-free version, skip the cheese or use a plant-based alternative. You can also swap Italian sausage with chicken or turkey sausage for a leaner twist.

Equipment Needed

• Crockpot or slow cooker: A 6-quart (5.7 liters) crockpot works perfectly for this recipe. If yours is smaller, adjust quantities accordingly.
• Knife and cutting board: For slicing peppers, onions, and garlic.
• Spoon or tongs: To turn sausage halfway through cooking if desired.
• Skillet (optional): For browning sausage before crockpot if you want extra caramelization—though this step is totally optional.
• Measuring spoons: To get your herbs and seasoning just right.

If you don’t have a crockpot, a slow cooker insert on a low setting or even a Dutch oven in the oven at low heat can work with some timing adjustments. For budget-friendly options, there are affordable crockpots around $20-$30 that do the job just fine. I’ve found that a ceramic insert crockpot holds heat evenly, making the sausage tender and juicy every time.

Preparation Method

1. Prep the veggies: Slice 3 bell peppers into thin strips and 1 large onion into thin slices. Mince 3 garlic cloves. This should take about 10-15 minutes. The thinner the slices, the more tender they become in the crockpot.
2. Optional browning: If you want, brown the sausage links in a skillet over medium heat for about 3-4 minutes per side until golden. This adds extra flavor but isn’t necessary. Don’t worry if you skip this step; slow cooking will do the magic.
3. Layer ingredients: In the crockpot, pour 1 tablespoon olive oil and add the sliced peppers, onions, and garlic. Nestle the sausage links on top. Sprinkle 1 teaspoon dried oregano, 1 teaspoon dried basil, 1/4 teaspoon red pepper flakes (if using), and season with salt and black pepper to taste.
4. Add tomatoes: Pour in 1 can (14.5 oz / 411 grams) crushed tomatoes or marinara sauce over the top. Give a gentle stir to combine the seasonings with the veggies but keep the sausage mostly on top for even cooking.
5. Cook low and slow: Cover and cook on low for 4 hours or on high for 2 hours. The sausage should be fully cooked through with an internal temperature of 160°F (71°C). The peppers will be soft but not mushy, and the sauce will be thickened slightly.
6. Check halfway: About halfway through cooking, you can carefully turn the sausage links with tongs for even cooking and flavor distribution if you like.
7. Prepare the rolls: When the sausage and peppers are nearly done, preheat your oven to 350°F (175°C). Slice your rolls lengthwise but not all the way through, keeping them hinged.
8. Assemble the sandwiches: Place cooked sausage links along the rolls, spoon generous amounts of peppers and sauce over each. Add a slice of provolone cheese on top if desired.
9. Melt the cheese: Place the assembled sandwiches on a baking sheet and bake in the oven for 5-7 minutes or until the cheese melts and the bread is slightly toasted.
10. Serve warm: Remove from oven, let cool a minute or two, then serve with your favorite sides or a crisp salad.

Troubleshooting tip: If your peppers seem too watery after cooking, let the crockpot cook uncovered for the last 30 minutes to thicken the sauce. Also, don’t overfill the crockpot—it’s better to cook in batches than overcrowd, which can make the sausage steam instead of brown.

Cooking Tips & Techniques

Honestly, the crockpot method is forgiving, but a few insider tips can really make your Easy Crockpot Sausage and Peppers Sub Sandwiches shine. First off, don’t rush the cooking time. Low and slow is your friend here—it lets the sausage juices mingle with the peppers and sauce for that rich, hearty bite.

One mistake I made early on was skipping the proper slicing of peppers and onions. Thick chunks take longer to soften, so take a little extra time to slice thinly. You’ll thank yourself when the peppers practically melt in your mouth.

Another pro tip: use good-quality Italian sausage—it really makes a difference. I’ve found sausages with natural casings add a nice snap and lock in juices better.

When assembling sandwiches, resist the urge to pile on too much sauce or it can make the bread soggy. Spoon just enough to coat the sausage and peppers. Also, to save time, you can prep the peppers and onions the night before and store them in the fridge.

Multitasking tip: while the crockpot does its magic, use that time to prepare a simple side salad or your favorite chips—easy cleanup and a balanced meal.

Variations & Adaptations

This recipe is flexible and lends itself well to tweaks depending on what you have or your dietary needs.

• Vegetarian version: Swap sausage for plant-based Italian sausages or use hearty mushrooms like portobello or cremini for a meaty texture.
• Spicy boost: Add sliced hot cherry peppers or extra red pepper flakes for a fiery kick. You can also use spicy Italian sausage instead of mild.
• Cheese options: Try mozzarella, fontina, or sharp provolone for different melty textures and flavors.
• Cooking method: Instead of crockpot, you can cook everything in a Dutch oven on the stovetop over low heat for about 45 minutes, stirring occasionally.
• Gluten-free adaptation: Use gluten-free sub rolls or serve the sausage and peppers over rice or polenta.

One of my favorite variations is to add a splash of balsamic vinegar at the end of cooking—it adds a subtle tang that brightens the flavors wonderfully.

Serving & Storage Suggestions

These sausage and peppers subs are best served warm, fresh out of the oven when the cheese is perfectly melted and the bread has a slight crunch. For presentation, garnish with fresh basil or parsley for a pop of color and freshness.

They pair beautifully with a crisp green salad, crunchy pickles, or classic potato chips. For drinks, a cold beer or a glass of red wine complements the rich flavors nicely.

Leftovers store well in an airtight container in the refrigerator for up to 3 days. To reheat, wrap sandwiches in foil and warm them in the oven at 350°F (175°C) for about 10-15 minutes to keep the bread from getting soggy. You can also microwave covered loosely with a paper towel for 1-2 minutes, but the bread might lose some crunch.

Flavors deepen the next day, so sometimes I make these in advance for a meal that tastes even better warmed up. Just keep the bread separate if you plan to store sandwiches assembled to avoid sogginess.

Nutritional Information & Benefits

Each sandwich provides roughly 450-550 calories depending on sausage and bread choices. They offer a satisfying balance of protein, healthy fats, and carbs, making it a filling meal.

Bell peppers are rich in vitamin C and antioxidants, which support immunity and skin health. Using olive oil adds heart-healthy monounsaturated fats, and fresh garlic offers natural anti-inflammatory benefits.

This recipe can be adapted to be gluten-free and dairy-free by swapping bread and cheese. It’s a hearty option that avoids overly processed ingredients, especially if you choose high-quality sausages.

From my wellness perspective, this meal feels indulgent without being heavy or greasy when made with quality ingredients and paired with fresh sides.
