• Tomato Sauce – 1 can (15 oz)
• Diced Tomatoes – 1 can (14.5 oz), preferably fire-roasted for added depth
• Olive Oil – 1-2 tablespoons
• Italian Seasoning – 2 teaspoons
• Crushed Red Pepper Flakes – ½ teaspoon (optional, for heat)

Optional additions:

Instruction Guide

Here’s the step-by-step process, broken down so it’s easy to follow:

1. Prep The Ingredients

   • Slice the bell peppers into thin strips.
   • Slice the onions into rings or half-rings.
   • Mince the garlic cloves.

2. Brown The Sausages (Optional But Recommended)

   • Heat a skillet over medium heat with a little olive oil.
   • Brown the sausages on all sides for 5-6 minutes. This locks in flavor and adds a deeper richness to the sauce.

3. Layer The Ingredients In The Slow Cooker

   • Start with a drizzle of olive oil on the bottom.
   • Add half the onions and bell peppers.
   • Place the sausages on top.
   • Add the remaining onions and peppers.
   • Pour the tomato sauce and diced tomatoes over everything.
   • Sprinkle garlic, Italian seasoning, crushed red pepper flakes, salt, and pepper.

4. Cook Low And Slow

   • Cover and cook on low for 6-7 hours or high for 3-4 hours.
   • The longer cooking time allows flavors to meld beautifully.

5. Finish And Serve

   • Taste and adjust seasoning if necessary.
   • Garnish with fresh basil or parsley.
   • Serve over pasta, polenta, rice, or in a sandwich roll for an Italian sub twist.

Ingredient Swaps

If you want to mix things up or accommodate what’s in your pantry:

• Sausages: Chicken or turkey sausage for a leaner option; or even vegetarian sausage for a plant-based version.
• Peppers: Use poblano, Anaheim, or even roasted red peppers for a slightly different flavor.
• Tomatoes: Substitute with crushed tomatoes, tomato puree, or fresh tomatoes for a lighter sauce.
• Onions: Sweet onions or shallots work nicely for a milder, sweeter flavor.
• Spices: Add fennel seeds for a traditional Italian note, or smoked paprika for a smoky depth.

Helpful Tips

• Don’t skip browning the sausages-it adds caramelized flavor that elevates the dish.
• Cut veggies evenly so they cook uniformly.
• Taste before serving-slow cookers can sometimes mellow flavors, so a little extra seasoning at the end can make a big difference.
• Stir occasionally if possible, especially if cooking on high. This prevents sticking and ensures even sauce distribution.
• Leftovers: This dish keeps beautifully in the fridge for up to 4 days and tastes even better the next day.

Customization Ideas

Make this dish truly yours by experimenting:

• Cheesy Delight: Top with mozzarella or Parmesan in the last 30 minutes.
• Spicy Kick: Use hot Italian sausage and add extra red pepper flakes.
• Herb Garden: Mix in fresh rosemary, thyme, or oregano for more herbaceous notes.
• Mediterranean Twist: Add olives and capers for a tangy variation.
• Comfort Carbs: Serve with creamy polenta or over garlic butter noodles for an indulgent version.

FAQs

What Type Of Italian Sausage Is Best For Slow Cooker Recipes?

For slow cooker recipes, both sweet and hot Italian sausages work well. Sweet sausage provides a milder flavor, while hot sausage adds a bit of spice. Pre-cooked or raw sausages can be used, but raw sausages allow flavors to meld better during slow cooking.

Do I Need To Brown The Sausage Before Adding It To The Slow Cooker?

Browning the sausage before slow cooking is optional but recommended. It enhances the flavor through caramelization and helps the sausage hold its shape. However, you can skip this step if you’re short on time.

Can I Use Frozen Sausage In A Slow Cooker?

Yes, frozen sausage can be used, but cooking time will need to be extended by 30-60 minutes to ensure the meat is fully cooked. For best results, thaw the sausage before adding it to the slow cooker.

What Vegetables Work Best With Italian Sausage In A Slow Cooker?

How Long Should I Cook Italian Sausage And Peppers In A Slow Cooker?

How Can I Make The Peppers Tender But Not Mushy?
