Ingredients

Scale
  • 8 slices thick-cut bacon
  • 2 large yellow onions, thinly sliced
  • 2 cups shredded cheddar cheese
  • 1 cup sour cream
  • 1/2 cup mayonnaise
  • 1/2 cup whole milk
  • 2 tablespoons all-purpose flour
  • 1/2 teaspoon garlic powder (or 1 small clove, minced)
  • 1/2 teaspoon black pepper
  • 1/4 teaspoon salt
  • 2 tablespoons chopped fresh parsley (optional)
  • 1 sleeve Ritz crackers (about 30 crackers)
  • 1/4 cup unsalted butter, melted
  • 1/4 cup grated Parmesan cheese (optional)

Instructions

  1. Preheat oven to 350°F (175°C). Grease a 9×13-inch casserole dish with butter or nonstick spray.
  2. Place bacon strips in a cold skillet. Cook over medium heat until crisp, about 8-10 minutes, flipping as needed. Transfer to a paper towel-lined plate and chop into bite-sized pieces. Reserve 1 tablespoon bacon grease.
  3. Add sliced onions to the skillet with reserved bacon grease. Cook over medium-low heat, stirring often, until golden and soft, about 10-12 minutes. Add a splash of water if onions start sticking.
  4. In a medium mixing bowl, whisk together sour cream, mayonnaise, milk, flour, garlic powder, pepper, and salt until smooth. Stir in shredded cheddar and parsley.
  5. Fold caramelized onions and chopped bacon into the creamy mixture. Pour into prepared casserole dish and spread evenly.
  6. Place crackers in a zip bag or between wax paper and crush lightly. In a small bowl, mix melted butter with crushed crackers and Parmesan cheese (if using). Sprinkle evenly over casserole.
  7. Bake on center rack for 25-30 minutes, until topping is golden and edges are bubbly. Cover loosely with foil if topping browns too quickly.
  8. Remove from oven and let rest for 5-10 minutes before serving. Garnish with extra parsley if desired.

Notes

Caramelize onions slowly for best flavor. Use thick-cut bacon for extra crunch. Shred your own cheese for a creamier texture. Prep bacon and onions ahead to save time. For gluten-free or dairy-free adaptations, see ingredient substitutions. Topping can be broiled briefly for extra crunch.
