This simple one skillet French Onion Tater Tot Casserole is the perfect pantry staple recipe to make any time of year. It’s a cross between french onion soup and a classic midwest style tater tot casserole. Slowly caramelized onions, white wine, vegetables, and beef or chicken…all cooked together in one skillet. Then topped off with plenty of cheese, tater tots, and fresh herbs. Simply toss the skillet in the oven to create the perfect cheesy, one skillet dinner. There’s nothing not to love. This dish is easy, takes just about an hour to make, is cheesy, heavy on the potatoes, and all-around delicious!

You guys, this quarantine cooking is getting, well…it’s getting interesting. The honest truth? I have mixed feelings about this recipe. Yes, this is delicious, it’s hearty, it’s cozy, it’s easy, and it’s full of pantry and freezer staples. It’s is THE “quarantined” dinner.

But? It’s also not my usual style of cooking. Or at least not the usual type of recipe I share here on HBH. When my brothers are in Colorado, I cook them their favorites…chicken noodle casserole, potato chip chicken, and basically all the old school Gerard family childhood favorites of our midwest roots. However, I don’t usually share these recipes. But times are a little different right now. I know everyone is in the same boat…cooking with what we’ve got on hand. Using pantry staples and creating simple but delicious recipes for our families during this time.

And that’s where this casserole comes into the story. A week or so ago, I shared on my Instagram stories that I had a bag of frozen tater tots in my freezer. Immediately our Instagram direct messages were flooded with requests for tater tot recipes. And the most requested?

A classic tater tot casserole, also known as tater tot hot dish. Soooo…this is my spin. And although I’m nervous to share it…it is different, it’s also so delicious. My oldest brother, Creighton, a tater tot loving kind of guy fully approves. So you know this is good.

The details on this one skillet french onion tater tot casserole…

As always, step one is finding yourself a great skillet. This is the exact matte black one I am using in these photos. But as I’ve mentioned before, it also comes in this pretty blue color. I love the slightly larger and deeper eleven-inch skillet, but any oven-safe skillet will work great for this recipe. And if you don’t have an oven-safe skillet, just cook everything on the stove, then transfer the food to a baking dish. Use what you’ve got and make it work!

Start with the onions. They need to be deeply caramelized, just as you do when making French onion soup. My secret to the best caramelized onions…butter. And in today’s case…some dry white wine too.

The butter is used for obvious reasons – fat, flavor, and deliciousness. The wine is pretty traditional in most French onion soups, so I wanted to carry those flavors over into this casserole. You’ll cook about half of the wine into the onions. This not only helps the onions to caramelize quickly and evenly, it also infuses the onions with incredibly rich flavor.

If you prefer not to cook with wine, I recommend using about half a cup of apple juice or apple cider when caramelizing the onions. If you don’t have either of those, use broth. As for the remaining amount of wine (another half cup), use chicken or vegetable broth.

Once the onions have caramelized, push them to one side of the pan, add the meat, bell pepper (or mixed frozen vegetables), garlic, and seasonings. Allow the meat to brown, then add the remaining wine and a splash the soy sauce. The soy sauce may seem odd, but just trust me on this, it adds a layer of salty savory flavor.

Next, add a touch of flour, this helps thicken the sauce and make it almost gravy-like.

Remove from the heat and top the skillet with cheese, preferably Gruyere, which makes this similar in flavor to the classic bowl of french onion soup. If you don’t have Gruyere, use Swiss, cheddar, mozzarella, or whatever else you’ve got on hand. All cheese is delicious.

Onto the tater tots.

Here’s the KEY to this dish. I knew that if I was going to cook tater tots, they needed to be extra crispy, not soft and soggy.

So, first…keep those tots frozen until the directions say to place them over top of the cheese.

Second…you need to add that layer of cheese over the meat before adding the tots. The cheese acts as a barrier between the sauce and the tots preventing the tots from getting soggy.

At this point transfer the skillet to the oven, bake until the tater tots are golden. Remove and add the remaining cheese. About fifteen minutes later, you’ll have tater tot casserole with extra crispy, cheesy tater tots sizzling away on op.

It. Is. Good.

And that’s it. Simple right? This dish smells incredible as it bakes away in the oven, but it tastes even better.

The toppings.

This brings me right to the toppings, which I actually kept kind of simple. But sometimes simple is really all you need.

I topped this cheesy bake with fresh chives and thyme. That’s it, I know, it’s shocking, but tater tots are not fancy food, so you know? I skipped the fancy toppings and it’s OK.

What’s great about this one skillet cheesy tater tot casserole is that it incorporates a variety of flavors and textures. Yet it’s all made simply in ONE skillet, using all pantry staple ingredients.

Well, almost all pantry staples. If you don’t have a fresh bell pepper on hand, use a mix of frozen vegetables. Or anything from your fridge that you need to use up.

My only suggestion? Add a fun cocktail to livin’ up your Thursday night. This blueberry lemon thyme smash from last week is my current pick.

Ingredients

Instructions

  • 1. Preheat the oven to 425 degrees F.
    2. In a large oven safe skillet, melt the butter, olive oil, and onions together. Cook, stirring occasionally until softened, about 5 minutes. At this point, you want to slowly add 1/2 cup of the wine, 1/4 cup at a time, until the wine cooks into the onions. Continue to cook another 8-10 minutes until you've used the 1/2 cup of wine and the onions are deeply caramelized. Push the onions to the side of the pan and stir in the meat, bell pepper, garlic, thyme, parsley, cayenne, and season with salt and pepper. Cook, breaking up the meat as it cooks, another 5 minutes until the meat is browned. Stir in the flour and cook another minute. Add the remaining 1/2 cup wine, soy sauce, Worcestershire sauce, and 1 cup of water. Bring to a boil and simmer until thickened 3-5 minutes.
    3. Remove from the heat and sprinkle the Gruyere cheese overtop the meat. Arrange the tater tots on top of the cheese. Transfer to the oven and bake 20 minutes, until the tots are golden. Sprinkle the cheddar over the tater tots, return to the oven. Bake another 10-15 minutes, until the cheese is melted.
    4. Serve topped as desired with fresh thyme and chives.

Notes

To Make Vegetarian: Instead of using 1 pound of meat, use 3 cups of finely chopped mushrooms (can be any variety or a mix of varieties) plus 1 cup of finely chopped cauliflower (or use an additional cup of mushrooms). Sauté the vegetables as directed to do so for the meat. The cooking times should be very similar, if not the same.

    I have no idea where I went wrong. The onions took almost an hour to caramelize. I used ground beef and browned it in the same pan but it made the dish incredibly oily. I ended up trying to save the dish by airfrying the tots and using a turkey baster to suck up the juice from the pan.

    1. Hi Allison! I am really sorry to hear that. Is there anything you could have done differently? xTieghan

    Insanely delicious! To make meatless, I used 1/2 mushrooms and 1/2 Morning Star Breakfast Sausage instead of the ground turkey. Thank you for another great recipe.

  3. Tried this for dinner tonight – yum! It helped me use up the tater tots I had in my freezer as well as produce that needed to be used (mushrooms, cauliflower, carrot). It all worked great with the turkey & onions. I used mozzarella cheese & cheddar as that was what I had on hand. Thanks so much for the recipe! Really love your posts as well as your cookbooks & your photos are amazing!!! : )

    We made the vegetarian version last night with both mushrooms and cauliflower last night, using apple juice for the wine. It was absolutely amazing! Even my burly sons loved it. Thank you so much!

    My kids and husband have started asking if it’s a “Tieghan Dish” before I even start cooking! They even mentioned this one wasn’t “normal” for you lol! But we loved it. Especially the teenagers. Thank you for bringing delicious meals to our house almost daily. You never fail us.

    Made this for dinner last night for my husband and 2 of my twenty something kids who are quarantining with us, everyone loved it. When my daughter saw me unloading the groceries a few days earlier and spied the tater tots, she asked “What did you buy those for, you know we’re not 5 anymore?” So when she asked what was for dinner, I said a chicken skillet recipe. She rolled her eyes. As they were eating it, going back for seconds, telling me how great it was and to make sure I made it again, I said you know those are the tater tots on top…she laughed and said yes but they are grown up tater tots.

    1. Haha wow that is amazing!! I am so glad you all loved this recipe, Deborah! Thank you! xTieghan

    Simple, comforting/nostalgic flavors, and filling! Thanks for this recipe! We’ve had it once as dinner and once as brunch (with a fried egg on top of each serving), both with using ground turkey as the meat option. We made the recipe exactly as written.
    Amazing both ways, and would highly recommend trying it as brunch!
    I think next time we make it as a brunch, I might try the mushroom/cauliflower vegetarian version and still include a fried egg on top of each serving.

  11. We tried this last night and enjoyed it very much but I have a bit more than half the skillet left. What is the best way to warm it up for dinner again so that the tater tots will be crispy again? I hope you’ll see this and reply today.

    1. Hi Jo,
      Thanks so much for trying the recipe! I would recommend heating in the oven on low. xTieghan
