Ingredients:
- lbs Lean Ground Beef (85/15 or 90/10)
- medium Yellow Onion, finely diced
- cloves Garlic, minced
- tsp Salt
- ½ tsp Black Pepper
- Tbsp Worcestershire Sauce
- Tbsp Unsalted Butter
- Tbsp All-Purpose Flour
- ½ cups Low-Sodium Beef Broth
- ½ cup Milk (whole or 2%)
- Tbsp Dijon Mustard
- Tbsp Ketchup
- tsp Yellow Mustard
- tsp Apple Cider Vinegar
- oz Egg Noodles, uncooked
- cups Sharp Cheddar Cheese, shredded (divided)
- cup Dill Pickle Chips or Bread & Butter Chips, drained and roughly chopped
- ½ cup Panko Breadcrumbs (optional)
- Tbsp melted Unsalted Butter (optional, for topping)
- Sesame Seeds (optional)
Instructions:
- Preheat oven to 375°F (190°C). Cook egg noodles according to package directions until al dente (slightly undercooked). Drain well and set aside.
- Brown the ground beef in a large skillet over medium-high heat. Drain off excess fat thoroughly. Add diced onion and sauté until softened (about 5 minutes). Stir in minced garlic, salt, pepper, and Worcestershire sauce; cook for 1 minute until fragrant. Remove from heat.
- Melt the 2 Tbsp butter in the skillet. Whisk in the flour and cook for 1 minute to form a roux. Gradually whisk in the beef broth until smooth. Bring to a gentle simmer, whisking constantly until the mixture thickens slightly.
- Remove the sauce from the heat. Whisk in the milk, Dijon mustard, ketchup, yellow mustard, and vinegar until fully combined and smooth.
- Gently fold the cooked noodles, the beef mixture, most of the cheddar cheese (reserving ½ cup), and the chopped pickles into the creamy sauce until everything is evenly coated.
- Transfer the mixture into a prepared 9x13 baking dish. Sprinkle the reserved ½ cup of cheddar cheese evenly over the top. (Optional: Mix Panko breadcrumbs with 2 Tbsp melted butter and sesame seeds; sprinkle over the cheese.)
- Bake for 30–35 minutes, or until the casserole is bubbly around the edges and the cheese topping is melted and lightly golden.
- Let the Cheeseburger Casserole rest for 5–10 minutes before scooping and serving.
