How to Make Sloppy Joe Casserole

  1. Boil Potatoes and Garlic – In a large pot, combine Yukon Gold potatoes, garlic, and kosher salt; cover with water and simmer until fork-tender, about 10-15 minutes. Drain and return the potatoes to the pot.

  2. Brown Ground Beef – Heat extra virgin olive oil in a large oven-safe skillet over medium-high heat. Add lean ground beef and cook until browned, around 7 minutes. Set the beef aside once cooked.

  3. Sauté Vegetables – In the same skillet used for the beef, add yellow onion, red bell pepper, and carrots; cook until softened, roughly 5 minutes. Then, stir in garlic, chili powder, and tomato paste; continue to cook for 1 more minute.

  4. Prepare Mashed Potatoes – Mash the drained potatoes with buttermilk and salt until smooth and creamy. Adjust the consistency as desired for a fluffy topping.

  5. Finish Filling – Return the browned beef to the skillet and stir in beef broth, ketchup, Worcestershire sauce, Dijon mustard, brown sugar, and red wine vinegar. Let simmer until thickened, about 3-4 minutes.

  6. Assemble Casserole – Spread the creamy mashed potatoes evenly over the beef mixture in the skillet. Sprinkle shredded cheddar cheese generously on top.

  7. Bake – Preheat the oven to 375°F. Bake the casserole for 10-15 minutes until the cheese is melted and the edges bubble. Broil for an additional minute if you’d like a golden-brown finish.

  8. Rest and Serve – Allow the casserole to rest for 5 minutes before serving. Garnish with chopped green onions for an added fresh crunch and enjoy!

Optional: For a spicy kick, sprinkle some crushed red pepper flakes on top before baking.
