How to make sausage potato casserole

Preheat oven to 400 degrees F and prepare a 9 x 13 baking dish with non-stick cooking spray.

Rinse baby red potatoes and slice in half using a cutting board and knife. You may want to cut it into smaller pieces if casserole is being served to children. Transfer potatoes into a gallon-size zip lock bag.

Ziplock bag with olive oil and seasoned potatoes.

Add 1/4 cup olive oil, black pepper, salt, smoked paprika, and onion powder over the potatoes and seal bag securely.

Give the zip lock bag a thorough shake to coat all surfaces of the potato pieces, and set the bag aside.

Pour 1/4 cup water into a large frying pan, add sliced sausage pieces, and cook over medium heat. When the sausages reach a slightly browned exterior, most of the water will be evaporated.

Frying pan of melted butter, onions and garlic.

Move the cooked sausage into a bowl and combine it with the seasoned potatoes from the bag.

Using the same frying pan, melt 1/4 cup of butter and add in chopped onion and garlic. Saute until onions become translucent.

Combine the onion mixture with the sausage and potatoes and incorporate the green beans. Mix gently to allow spices to cover all the ingredients.
