👩‍🍳 How to Make Sausage, Green Bean, & Potato Casserole

1. Preheat and prep

Preheat your oven to 400°F (200°C). Grease a large baking dish or casserole pan.

2. Prepare the vegetables

Slice potatoes into halves or quarters. Trim the ends off the green beans and slice the onion.

Place potatoes, green beans, onions, and minced garlic into the casserole dish.

3. Add the sausage

Slice the smoked sausage into ½-inch pieces and scatter over the vegetables.

4. Mix the seasoning butter

In a small bowl, combine melted butter, olive oil, garlic powder, onion powder, smoked paprika, pepper, and salt.
Pour the mixture evenly over the sausage and vegetables.

Use clean hands or a spoon to toss everything until well coated.

5. Cover and bake

Cover with foil and bake for 40 minutes, stirring halfway.

6. Uncover and finish baking

Remove the foil and bake for another 10–15 minutes until potatoes are tender and the edges are slightly crisp.

For a golden top, broil for 2–3 minutes at the end.

7. Serve hot

Garnish with parsley, cheese, or extra seasonings if desired.
Enjoy warm as a stand-alone meal!

🍽️ Serving Suggestions

This casserole is perfect on its own but pairs wonderfully with:

Fresh dinner rolls

A side salad
Cornbread
Roasted carrots

Coleslaw

You can also drizzle with ranch dressing or spicy mayo for added flavor!

🔄 Recipe Variations

1. Cheesy Casserole

Sprinkle 1–2 cups shredded cheddar or mozzarella over the top during the last 10 minutes of baking.

2. Creamy Version

Stir a can of cream of mushroom or cream of chicken soup into the mixture before baking.

3. Spicy Kick

Use spicy sausage or add cayenne pepper, Cajun seasoning, or red pepper flakes.

4. Sheet Pan Style

Spread ingredients on a baking sheet instead of a casserole dish for crispier potatoes and green beans.

5. Slow Cooker Version

Cook on LOW for 6–7 hours or HIGH for 3–4 hours. Add green beans halfway through for best texture.

🧊 Storage & Reheating

Store:

Refrigerate leftovers in an airtight container for up to 4 days.

Freeze:

Freeze portions for up to 3 months. Thaw before reheating.

Reheat:

Warm in the oven at 350°F or in a skillet.
Microwaving works too, though potatoes may soften more.

📌 Tips for the Best Casserole

Use fresh green beans for the best texture.
Slice potatoes evenly so they cook at the same rate.

Don’t skip the butter—it adds richness and helps caramelization.
Stir halfway through for even cooking.
Broil at the end if you love crispy sausage edges.
