Ingredients
- Andouille sausage: adds smoky, Cajunstyle flavor and hearty protein choose quality sausage with good seasoning for best results
- Yellow onion: provides a sweet, savory base that melts into the dish look for firm, unblemished onions
- Baby potatoes: hold their shape well and become creamy inside pick evenly sized to cook uniformly
- Green beans: fresh and trimmed adds color, texture, and a slight snap fresh is preferred but frozen works too
- Fresh garlic: freshly minced garlic elevates the flavor significantly avoid preminced for better aroma and taste
- Dry onion soup mix: a seasoning shortcut loaded with savory flavor opt for your favorite brand or homemade blend for freshness
- Butter: melts into a luscious finish that brings all ingredients together use unsalted for control over seasoning
- Parsley: optional garnish for a pop of color and freshness pick vibrant green sprigs
Instructions
- Sauté the Aromatics:
- This dish is all about the slow cooker dump and go, so no sautéing necessary here. Simply slice your yellow onion and mince your fresh garlic. These will soften beautifully as they cook slowly alongside the other ingredients.
- Combine Ingredients in the Slow Cooker:
- Add your halved baby potatoes, sliced andouille sausage, trimmed green beans, sliced onion, and minced garlic directly into your slow cooker. This layering ensures flavors meld beautifully.
- Add Dry Onion Soup Mix:
- Sprinkle the dry onion soup mix evenly over the top. This packet is your flavor powerhouse, seasoning everything richly without the need for extra salt or complex spice blends.
- Stir and Add Butter:
- Gently stir the ingredients so the seasoning coats evenly but potatoes stay intact. Slice your butter into pieces and place them on top. The butter will melt and infuse the whole dish with a creamy richness that elevates the potatoes and sausage.
- Cook Until Tender:
- Cover and cook on low for six hours or on high for four hours. The potatoes should be tender when pierced with a fork and everything will smell irresistible. Resist the urge to disturb the pot too frequently; slow cooking works best with minimal peeking.
- Garnish and Serve:
- If you’re feeling fancy, sprinkle freshly chopped parsley on top for color and bright flavor contrast. Serve warm, ideally with crusty bread to soak up the garlicky buttery sauce.

My favorite ingredient is definitely the andouille sausage because its smoky heat carries the whole dish. I remember making this for a big family game day and watching everyone gather around the slow cooker multiple times, savoring each bite. It’s one of those recipes that always sparks conversation and requests for seconds.
Storage Tips
Store leftovers in an airtight container in the refrigerator for up to four days. Reheat gently on the stove or in the microwave to avoid drying out the potatoes. This dish also freezes well; just thaw overnight in the fridge before reheating.
Ingredient Substitutions
Use smoked sausage or kielbasa if you can’t find andouille. For a lighter version, turkey sausage works nicely. Green beans can be swapped with frozen versions or even broccoli or asparagus for a different vibe. If you don’t have onion soup mix, blend dried onion flakes, garlic powder, beef bouillon, and parsley to replicate the flavor.
Serving Suggestions
Pair this dish with warm crusty bread or garlic bread to mop up the buttery sauce. A crisp green salad balances the richness nicely. This meal stands on its own but also pairs well with simple coleslaw or pickled vegetables as refreshing sides.
