Classic Homemade Tater Tot Casserole

I have been making this Classic Homemade Tater Tot Casserole for about 3 years now but this is the first time it has made it to the blog.

It's nice for this time of year because it's a comfort food dish perfect for cold weather.

It's also a convenient one-dish dinner and though it does require a large frying pan to cook the ingredients, the cleanup from this dinner is relatively easy.

There is no condensed cream of mushroom canned soup in this recipe!

I will stop at making homemade tater tots though, at least for this recipe, let's just save that endeavor for another day. 🙂

Ingredients

• 1 lb.-2 lb. lean ground beef (adding more beef will just make it a little less saucy)
• 2 tablespoons unsalted butter, plus more for greasing pan
• 8 ounces sliced or chopped baby Portobello mushrooms
• 1 large onion, chopped (1-¼ cups)
• 3 cloves fresh minced garlic
• ½ cup all-purpose flour

• 1 tablespoon Worcestershire sauce (I used low sodium)
• ½ teaspoon kosher or sea salt
• ¼ teaspoon fresh ground black pepper, plus more for serving
• ¼ cup sour cream or plain Greek yogurt in the same amount, plus more for serving if desired

Ingredients

• 1 large onion, chopped (1-¼ cups)
• 3 cloves fresh minced garlic
• ½ cup all-purpose flour

Instructions

1. Preheat oven 350 degrees F. Grease a 13" x 9" x 2" inch casserole baking dish and set aside.
2. Brown the lean ground beef in a large skillet (pan) over medium-high heat until it is completely cooked. Using a slotted spoon, remove the cooked lean ground beef into a bowl and set it aside.
3. Melt butter in the same pan, add the mushrooms, garlic, and onion. Cook over medium heat until mushrooms are softened and the garlic and onion are translucent. Add in the cooked lean ground beef. Add the flour and combine the ingredients. Cook for 2 minutes.
4. Add beef stock and milk and combine. Add the ground thyme, Worcestershire sauce, kosher salt, and pepper, and combine. Bring to a simmer and allow to simmer 15-20 minutes. The mixture should be thick, yet saucy.
5. Remove the pan from the heat and stir in the sour cream or plain Greek yogurt. Stir in the green beans.
6. Pour the mixture into the casserole dish. Evenly spread ½ the cheese over the mixture. Arrange the tater tots on top in even layers. Spread the remaining cheese over the tater tots.
7. Bake for 45 minutes, the casserole should be bubbling and the top should be golden brown. Before serving top with chopped Italian parsley and an optional dollop of sour cream or plain Greek yogurt. Enjoy!
