Tater Green Bean Casserole

This potato green bean casserole takes the classic green bean side dish to a new level by adding diced potatoes and a creamy cheesy sauce. It’s a perfect holiday side that feels both familiar and freshly satisfying thanks to the crispy fried onions on top and the melty cheese throughout. This recipe has quickly become a favorite in my family because it’s comforting and hearty without being complicated.

I first made this casserole during a busy holiday season and was amazed how effortlessly it became the most requested side dish on the table. Everyone loved the extra texture and flavor the diced potatoes brought to the familiar green bean casserole.

Ingredients

• Cream of mushroom soup: The creamy base that binds everything together choose a good quality brand or make your own for the best flavor
• Milk: Whole milk is best for richness but 2 percent works fine too to keep it creamy
• Garlic salt: Adds subtle savory depth if you want to reduce sodium garlic powder works well
• Frozen O’Brien potatoes: These are perfectly diced potatoes mixed with peppers and onions for added flavor no thawing necessary
• Canned green beans: Convenient and tender canned work best here for consistent texture
• French’s Crispy Fried Onions: The classic topping that adds crunch and that signature green bean casserole touch
• Shredded cheese: I prefer a blend of Colby and Monterey Jack for meltiness and mild flavor but cheddar gouda or gruyere are great alternatives

Instructions

Sauté the Aromatics and Mix Ingredients:

In a large bowl, whisk together the cream of mushroom soup, milk, garlic salt, and black pepper until smooth. Stir in the frozen O’Brien potatoes, canned green beans, one and a third cups of crispy fried onions, and one cup of shredded cheese. Make sure to mix evenly so every bite has flavor.

Prepare to Bake:

Preheat your oven to 350 degrees Fahrenheit. Pour the combined mixture into a 9 by 13inch baking dish, spreading it evenly to ensure consistent cooking throughout.

Bake the Casserole:

Place the baking dish uncovered into the oven and bake for 30 minutes until the casserole is hot and bubbly, the cheese is melted inside, and the potatoes are tender.

Add Finishing Touches:

Remove the casserole from the oven and evenly sprinkle the remaining one cup of shredded cheese and one and a third cups of crispy fried onions on top. Return to the oven and bake for an additional five minutes until the cheese melts and the onions turn golden brown.

Serve and Enjoy:

Spoon out hearty portions onto plates and enjoy immediately. This casserole shines warm and pairs beautifully with any holiday main dish.

My favorite part of this casserole has to be the crispy fried onions on top. They bring a perfect crunch contrast to the creamy filling that really elevates the dish. I remember one Thanksgiving when I doubled the onions by accident, and it turned out to be such a hit that I never go back to using less.

Storage Tips

Store any leftovers covered tightly in the refrigerator and consume within three days to keep freshness. To reheat, cover loosely with aluminum foil and warm gently in the oven until heated through.

Ingredient Substitutions

If you cannot find O’Brien potatoes, you can substitute frozen shredded hash browns or finely dice fresh potatoes and parboil them first to ensure even cooking. For cream of mushroom soup alternatives, cream of chicken or cream of celery soups work nicely without overwhelming the flavor.

Serving Suggestions

This casserole pairs wonderfully with roast turkey, ham, or even grilled chicken for a cozy holiday meal. Add a crisp green salad or some crusty bread to complement the creamy texture.

This casserole is a comforting holiday staple that is easy to make ahead and always popular. Warm and crispy it complements roast mains and family gatherings.
