Ingredients
Main Ingredients
- Kosher salt (to taste)
- 8 oz. elbow macaroni
- 1 lb. ground beef
- 1 large yellow onion, finely chopped
- 3 cloves garlic, finely chopped
- 1 (14-oz.) can diced tomatoes
- 1/2 cup mayonnaise
- 1/4 cup chopped dill pickles
- 1/4 cup ketchup
- 2 tbsp. Worcestershire sauce
- 2 tbsp. yellow or Dijon mustard
- 1 tsp. freshly ground black pepper
- 6 oz. shredded cheddar cheese (about 1 1/2 cups), divided
- 2 tbsp. toasted sesame seeds (optional)
- 1 head romaine lettuce, chopped
Instructions
- Cook Pasta: Preheat your oven to 400°F. Bring a medium pot of water to a boil and season it with kosher salt. Add the elbow macaroni and cook, stirring occasionally, until very al dente — about 2 minutes less than the package directs. Drain the pasta and transfer it to a 13" x 9" baking dish.
- Brown Beef: While the pasta cooks, heat a large skillet over medium-high heat. Add the ground beef in large chunks and let it cook undisturbed for about 4 minutes to develop a deep brown crust on the bottom. Then break it up with a spatula and continue cooking, stirring occasionally, until the beef is fully browned and no pink remains, about 4 minutes more. Transfer the cooked beef to the baking dish over the pasta.
- Sauté Aromatics and Combine Sauce: Lower the heat to medium and add the chopped onion and garlic to the skillet. Cook, stirring occasionally, until they soften and become translucent, about 5 to 7 minutes. Stir in the diced tomatoes, mayonnaise, pickles, ketchup, Worcestershire sauce, mustard, 1 cup water, freshly ground pepper, and 1 teaspoon salt. Mix thoroughly and transfer this sauce mixture into the baking dish with the pasta and beef.
- Add Cheese: Stir in 3 ounces of the shredded cheddar cheese until evenly distributed throughout the casserole. Sprinkle the remaining 3 ounces of cheddar cheese evenly on top, and optionally sprinkle toasted sesame seeds if using.
- Bake: Place the casserole in the preheated oven and bake for 10 to 12 minutes, or until the cheese is melted and bubbly.
- Finish and Serve: Remove the casserole from the oven and sprinkle the chopped romaine lettuce on top just before serving for a fresh, crisp contrast.
- Make Ahead Tip: The casserole can be fully assembled without baking up to 1 day in advance. Cover with foil and refrigerate. When ready to serve, bake in a preheated oven at 400°F for 12 to 15 minutes until heated through and bubbly.
Notes
- For added crunch and flavor, sprinkle toasted sesame seeds on top before baking (optional).
- Make sure not to overcook the pasta initially; it should be slightly underdone before baking as it will finish cooking in the oven.
- If you prefer, the mayonnaise can be replaced with sour cream for a different tangy creaminess.
- Adding fresh romaine right before serving provides a refreshing contrast to the warm casserole.
- This casserole can be stored in the refrigerator for up to 2 days after baking; reheat thoroughly before serving.
