The Best Big Mac Casserole (Low Carb)
Description
The Best Big Mac Casserole (Low Carb) reimagines the famous burger by turning its core ingredients into a baked dish. Diced russet potatoes are first roasted to a tender consistency, creating a stable base. Ground beef is cooked with diced bell pepper, onion, jalapeño, and seasoned with Worcestershire sauce and ranch seasoning to reproduce the familiar burger flavors. The casserole includes diced pickles and a shredded cheese topping to finish. A custom fry sauce blends mayonnaise, honey mustard, ketchup, garlic and onion powder, and dill pickle juice, providing a tangy, creamy dressing that enhances the assembled casserole.
The casserole delivers layered textures, from the tender roasted potatoes to the cooked ground beef and melted cheese topping. The preparation method allows the flavors to meld intensively, with leftovers tasting even better as they marry. Serving with shredded lettuce adds freshness and a crisp contrast. This dish serves as a filling meal and can be reheated easily, making it practical for multiple servings.
The recipe notes suggest topping with additional condiments like mustard, ketchup, or ranch for extra flavor. Leftovers can be kept refrigerated up to four days and reheat well in the microwave, preserving moisture. Adding fresh lettuce at serving time is recommended to maintain some crunch and brightness.
Ingredients
- 2 russet potatoes large
- 1 tbsp olive oil
- 1 tsp garlic powder
- 1 tsp onion powder
- pinch salt
- pinch black pepper
- 1 lbs ground beef 96% lean
- 1 tbsp Worcestershire sauce
- ½ cup white onion diced
- ⅓ cup bell pepper diced
- 1 tbsp jalapeño diced
- 1 can diced tomatoes drained
- ½ cup dill pickle coins
- ½ packet ranch seasoning
- ½ tsp sesame seeds
- ½ cup Colby-Jack cheese or shredded cheese of choice, reduced fat, shredded
- lettuce optional for serving, shredded
For the fry sacue:
- ¼ cup mayonnaise light
- 1 ½ tsp honey mustard
- 2 tsp ketchup low sugar
- ¼ tsp garlic powder
- ¼ tsp onion powder
- 2 tbsp dill pickle juice
Instructions
- Preheat the oven to 350°F and prepare the veggies. Slice potatoes into ~½ inch rounds, and then dice them into ½” cubes. Finely dice the white onion, bell pepper, and jalapeño, too.
- Add the diced potatoes to the casserole dish and coat in olive oil and salt + pepper. Pop them into the oven for 25 minutes. We’re coming back to them, but potatoes need longer to cook. Next, make the fry sauce and prep the ground meat mixture.
- For the fry sauce, combine all of the ingredients in a glass measuring cup or small bowl and stir. If you’d like, you can also add little pieces of diced pickle to the sauce for more texture. Store in the fridge until ready to use.
- Heat a skillet to medium heat and grease with cooking spray. Add the lean ground beef, diced bell pepper, onion, and jalapeño. Mix until the ground beef is ~80% cooked, then mix in the Worcestershire sauce and ranch seasoning. Allow the beef to cook through.
- By this time, the potatoes should be finished. Remove from the oven but keep the oven on. Add ground beef mixture, canned tomatoes (drained), and ½ of the fry sauce on top of the potatoes. Stir it all together.
- Top the dish cheese, pickles, and sesame seeds. Cover the casserole with tinfoil sprayed with cooking spray (tinfoil is a must, otherwise it will significantly dry out). Bake for another 20 minutes.
- Remove the tinfoil, serve with shredded lettuce and add remaining fry sauce. Enjoy!
Notes
- Additional condiments like mustard, ketchup, or ranch can be added on top to enhance flavor.
- Store the casserole in the refrigerator for up to 4 days; flavors improve after sitting overnight.
- Reheat in the microwave for 60-90 seconds until warmed through.
- Add fresh shredded lettuce just before serving for added texture and freshness.
