  • 8 slices of bacon chopped
  • 1 cup chopped yellow onion
  • 2 Tbsp. butter
  • 2 Tbsp. flour
  • 1 ¼ cups milk plus 2 Tbsp., divided
  • 3 cups shredded sharp cheddar cheese divided
  • ¾ cup sour cream divided
  • 1 cup chopped scallions divided
  • 1 32 oz package frozen tater tots divided
  • 1 Tbsp. chopped fresh chives
  • 1 Tbsp. chopped fresh dill
  • Pinch kosher salt and pepper


  • Preheat oven to 350°F.
  • Add bacon to a Dutch oven over medium heat.
  • Cook, stirring occasionally, until crispy, about 10 minutes.
  • Remove bacon with a slotted spoon; place bacon on a paper towel.
  • Discard all but 2 Tbsp. bacon grease from pan (reserve extra for another use).
  • Add onion to bacon grease in pan. Cook, stirring occasionally, until softened, about 5 minutes. Add butter to pan; let melt.
  • Stir flour into butter and onions. Cook, stirring, 2 minutes.
  • Stir in 1 ¼ cups milk until combined. Remove from heat.
  • Stir in 1 ½ cups cheese, ½ cup sour cream, and ½ cup scallions.
  • Stir in half of frozen tater tots; transfer mixture to a 13x9-inch baking dish. Sprinkle with remaining tater tots, bacon, and cheese.
  • Bake until bubbly, about 35 minutes. Let cool 5 minutes.
  • Stir together remaining ¼ cup sour cream, 2 tablespoons milk, chives, dill, and salt, and pepper in a small bowl until smooth.
  • Sprinkle remaining ½ cup scallions over casserole; drizzle with homemade ranch.


  • I like to use thick-cut bacon so it stays nice and meaty when cooked.
  • Cheddar cheese adds a classic flavor to this casserole; spice it up by using pepper jack instead!
  • Don’t worry about thawing the tots; they’ll warm up during baking.
  • You’ll notice I don’t add any salt to the casserole. I found it salty enough, but please feel free toseason it to taste.
  • The Homemade Ranch makes a great dressing for salad, which you’re probably going to want after this delicious indulgence. Or maybe not!
