How to Make Green Bean Casserole with Tater Tots: Irresistibly Cozy
Step 1: Prep Your Baking Dish
First things first—preheat your oven to 375°F and grease a 9×13-inch baking dish. This ensures your Green Bean Casserole with Tater Tots: Irresistibly Cozy won’t stick, so you’ll get every last cheesy scoop with ease.
Step 2: Sauté the Aromatics
In a large skillet over medium heat, melt the butter. Add the diced onion and sauté for 3 to 4 minutes until it’s soft and fragrant. Stir in the minced garlic and cook for 30 seconds, just until it releases that mouth-watering aroma—don’t let it brown!
Step 3: Make the Creamy Sauce
Sprinkle the flour over the cooked onions and garlic, then stir constantly for about 1 minute. This step builds the base for your sauce and helps avoid lumps. Slowly whisk in the milk, letting the mixture become smooth and slightly thickened. Stir in the sour cream, cream of mushroom soup, salt, pepper, and thyme (if you’re using it). Simmer for 2 to 3 minutes to marry all the flavors into a rich, velvety sauce.
Step 4: Build the Casserole
Take the skillet off the heat and gently fold in the green beans, followed by 1 cup of shredded cheddar cheese. Stir until everything’s evenly coated. Now, scoop this creamy mixture into your prepared baking dish and spread it out nice and even.
Step 5: Top with Tater Tots
Arrange the frozen tater tots in a single layer right on top of the casserole. Don’t skimp! You want a full, crunchy blanket to cover the creamy goodness below.
Step 6: Bake to Golden Perfection
Place the dish in the oven, uncovered, and bake for 35 to 40 minutes. Your kitchen will fill with the aroma of melting cheese and sizzling tater tots. When the tots are golden and crispy, sprinkle the remaining 1/2 cup cheddar over the top. Pop it back in the oven for another 5 minutes—just until that cheese is bubbly and irresistible.
Step 7: Let It Rest, Then Serve
Let the casserole rest for about 5 minutes before diving in. This helps everything firm up a bit and makes serving easier. Now, dig in and brace yourself for that glorious, homey bite!

Reheating
For best results, reheat casserole leftovers in a 350°F oven until heated through, which helps revive that delicious, crispy tater tot topping. In a pinch, the microwave works too—just know the texture might be a bit softer.
