How to Make the Recipe

In the same pan, lightly sauté onions, garlic, and bell peppers until softened.

Tips for Making the Recipe

• Brown the sausages before adding them to the slow cooker for a richer flavor.
• Don’t skip the aromatics—garlic and onions give the casserole a strong base.
• Cut vegetables evenly so they cook at the same rate.
• Use waxy potatoes like Yukon Golds to hold their shape during cooking.
• Add leafy greens like spinach at the end if you want a nutrition boost.

How to Serve

Serve the casserole piping hot with crusty bread, mashed potatoes, or rice to soak up the flavorful sauce. A side of green vegetables or a fresh salad complements it well. Garnish with fresh parsley for a pop of color and freshness.

Make Ahead and Storage

Storing Leftovers

Cool the casserole completely, then transfer to airtight containers. Refrigerate for up to 4 days.

Freezing

Portion into freezer-safe containers and freeze for up to 3 months. Defrost overnight in the fridge before reheating.

Reheating

Reheat on the stovetop over medium heat or in the microwave until piping hot. Add a splash of water or broth if the sauce has thickened too much.
