Step-by-Step Recipe Instructions

Follow these detailed steps to assemble and bake your Sausage Green Bean Potato Casserole flawlessly:

  1. Preheat & Prep
    • Preheat your oven to 375 °F (190 °C).
    • Lightly grease a 9×13″ baking dish with cooking spray or a thin brush of oil.
  2. Par-Cook the Potatoes
    • Wash and dice 1½ lbs of potatoes (Yukon Gold or Red Bliss) into ½″ cubes.
    • Spread potato cubes in a single layer on a baking sheet.
    • Drizzle with 1 Tbsp oil, season lightly with salt and pepper, and toss to coat.
    • Bake for 10 minutes, until just fork-tender. Remove and set aside.
  3. Brown the Sausage
    • Slice 1 lb of your chosen sausage (kielbasa, Andouille, or chicken-apple) into ½″ rounds.
    • In a large skillet over medium heat, add the sausage slices.
    • Cook 4–5 minutes, stirring occasionally, until edges are lightly browned.
    • Using a slotted spoon, transfer sausage to a paper-towel–lined plate.
  4. Sauté Aromatics & Green Beans
    • In the same skillet, add:
      • 1 medium yellow onion, diced
      • 3 cloves garlic, minced
    • Sauté 3–4 minutes, until translucent and fragrant.
    • Add 12 oz trimmed green beans (fresh or thawed frozen).
    • Sauté 2–3 minutes until beans turn bright green but remain crisp.
  5. Combine Casserole Filling

      • Par-baked potatoes
      • Browning sausage rounds
      • Sautéed onions, garlic, and green beans

  7. Crisp the Top

      • ½ cup shredded cheddar cheese (optional)
      • ¼ cup panko breadcrumbs (optional)
    • Return uncovered to the oven and bake 10 more minutes, until cheese is melted and breadcrumbs are golden.
