Here’s what you’ll need:

• 2 lbs Italian sausage (mild or spicy)
• 2 large onions, sliced
• 3 bell peppers, sliced (optional but recommended)
• 3 cloves garlic, minced
• 1 (14.5 oz) can diced tomatoes (optional for a saucier version)
• 1 tsp Italian seasoning
• ½ tsp black pepper
• ½ tsp salt (adjust to taste)
• 1 tbsp olive oil

Optional Additions and Substitutions

Make it your own with these ideas:

Tools You’ll Need

• Slow cooker
• Large skillet (optional, for browning)
• Cutting board and knife
• Tongs or spoon

How to Make Slow Cooker Sausage & Onions

Step 1: Brown the Sausage (Optional but Recommended)

Heat olive oil in a skillet over medium heat and brown the sausages on all sides. This step adds extra flavor but can be skipped if you’re short on time.

Step 2: Prep the Vegetables

Slice the onions and bell peppers, and mince the garlic. The more evenly they’re cut, the better they’ll cook.

Step 3: Layer Everything in the Slow Cooker

Add the onions and peppers to the bottom, then place the sausages on top. Sprinkle with garlic, seasoning, salt, and pepper.

Step 4: Add Liquid (Optional)

If using diced tomatoes, pour them over the top. This will create a delicious, slightly saucy base.

Step 5: Cook Low and Slow

Cover and cook on:

• LOW for 6–7 hours or
• HIGH for 3–4 hours

The sausages should be fully cooked and tender, and the onions beautifully softened.

Step 6: Serve and Enjoy

Serve whole or sliced, with plenty of those flavorful onions and juices spooned over the top.
