Recipe Info:
Prep Time: 15 minutes | Cook Time: 4-8 hours | Total Time: 4 hours 15 minutes | Yield: 6 servings

Ingredients

• 1 tablespoon olive oil (optional, for browning)
• 2 lbs Italian sausage, mild or hot (ensure low-carb/sugar-free)
• 1 large yellow onion, sliced
• 3 bell peppers (any color), cored and sliced
• 4 cloves garlic, minced
• 1 (28 ounce) can diced tomatoes, undrained (no sugar added)
• 1 (6 ounce) can tomato paste
• 1/2 cup chicken broth
• 2 teaspoons Italian seasoning
• 1 teaspoon salt, or to taste
• 1/2 teaspoon black pepper, or to taste
• Fresh parsley, chopped, for garnish (optional)

Step-by-Step Instructions

1. Brown the Sausage (Optional but Recommended): Heat olive oil in a large skillet over medium-high heat. Add the Italian sausage links and brown on all sides until nicely caramelized. This step adds a significant depth of flavor. You don’t need to cook them through, just get a good sear. Remove sausage from the skillet and set aside. If using ground sausage, crumble and brown, then drain excess fat.
2. Layer Ingredients in Slow Cooker: Place the sliced onions and bell peppers at the bottom of a 6-quart (or larger) slow cooker.
3. Add Aromatics and Tomatoes: Sprinkle the minced garlic over the vegetables. Pour in the undrained diced tomatoes, then add the tomato paste and chicken broth.
4. Season the Mixture: Stir in the Italian seasoning, salt, and black pepper, ensuring the spices are well distributed throughout the tomato mixture.
5. Add Sausage: Nest the browned Italian sausage links (or crumbled sausage) on top of the vegetable and tomato mixture.
6. Cook to Perfection: Cover the slow cooker and cook on LOW for 6-8 hours or on HIGH for 3-4 hours, or until the sausage is cooked through and the vegetables are tender. The sauce will thicken slightly and the flavors will meld beautifully.
7. Serve and Garnish: Once cooked, taste and adjust seasoning if necessary. Serve hot, garnished with fresh chopped parsley if desired.

Pro Tips for Success

• Don’t Skip the Browning: While optional, browning the Italian sausage before adding it to the slow cooker creates a rich, caramelized crust that significantly enhances the overall flavor of the dish. It locks in juices and adds a depth that simply simmering won’t achieve.
• Vary Your Peppers: Use a mix of red, yellow, and orange bell peppers not only for a beautiful visual appeal but also for a subtly varied sweetness and flavor profile. Green bell peppers are fine too, but can be a bit more bitter.
• Adjust Seasoning at the End: Slow cooking concentrates flavors, so it’s best to add a conservative amount of salt and pepper initially. Taste the dish once it’s fully cooked and adjust the seasoning as needed before serving.
• Mind the Moisture: The diced tomatoes and chicken broth provide plenty of liquid. Avoid adding too much extra liquid, as the slow cooker is designed to retain moisture, and you don’t want a watery sauce.

Variations & Substitutions

• Spicy Kick: For those who love heat, use hot Italian sausage instead of mild, or add a pinch of red pepper flakes to the sauce along with the other seasonings.
• Extra Veggies: Feel free to toss in other keto-friendly vegetables like sliced zucchini, mushrooms, or a handful of fresh spinach during the last 30 minutes of cooking for added nutrition and bulk.
• Dairy-Free Option: This recipe is naturally dairy-free, making it a great choice for those with sensitivities.
• Higher Protein: To boost the protein content even further, consider adding an extra link or two of sausage per serving, or serve alongside a grilled chicken breast.
• Ingredient Swaps: If you don’t have bell peppers, any sturdy low-carb vegetable like eggplant or even cabbage could work, though the flavor profile will change. Chicken sausage can be used as a lighter alternative to pork Italian sausage.

Serving Suggestions

This Keto Slow Cooker Italian Sausage & Peppers is a wonderfully versatile dish that pairs beautifully with a variety of low-carb sides. For a classic feel, serve it over a bed of fluffy cauliflower rice or spiralized zucchini noodles to soak up all that delicious sauce. Steamed green beans, roasted asparagus, or a simple side salad with a vinaigrette dressing make excellent fresh accompaniments. For those who enjoy a little something to dip, a slice of toasted low-carb bread or a keto-friendly roll would be perfect. This hearty meal is ideal for a satisfying weeknight dinner, a comforting Sunday supper, or as a fantastic make-ahead option for meal prep throughout the week.

Frequently Asked Questions

Can I use frozen Italian sausage?

Yes, you can use frozen Italian sausage. If the links are pre-cooked, you can add them directly to the slow cooker. If they are raw and frozen, it’s best to thaw them first for even cooking and browning (if you choose to brown them). If you don’t brown them, ensure they are separated before adding to the slow cooker to cook thoroughly.

Can I make this recipe ahead of time for meal prep?

Absolutely! This recipe is fantastic for meal prep. You can cook a large batch and portion it out into individual containers for quick and easy lunches or dinners throughout the week. The flavors often deepen and improve after a day or two in the refrigerator.

What if I don’t have a slow cooker?

No slow cooker? No problem! You can make this recipe in a large Dutch oven or a heavy-bottomed pot on the stovetop. After browning the sausage, add all ingredients, bring to a simmer, then cover and cook on low heat for 1-1.5 hours, stirring occasionally, until the sausage is cooked through and the vegetables are tender.
