🥖 Yield

  • Serves: 4–6 subs
  • Prep Time: 15 minutes
  • Cook Time: 25 minutes
  • Total Time: ~40 minutes

🧾 Ingredients

For the Sloppy Joe Filling

  • 1½ lb ground beef (80/20 or lean)
  • 1 small onion, finely diced
  • 1 green bell pepper, finely diced (optional but recommended)
  • 2 cloves garlic, minced
  • ¾ cup ketchup
  • 2 tbsp tomato paste
  • 2 tbsp Worcestershire sauce
  • 1½ tbsp brown sugar
  • 1 tsp yellow mustard
  • 1 tsp paprika
  • ½ tsp chili powder (optional)
  • ½ tsp salt (adjust to taste)
  • ½ tsp black pepper
  • ¼ cup water or beef broth

For Assembly

  • 4–6 sub rolls or hoagie buns
  • 2 cups shredded mozzarella, provolone, or Colby-Jack cheese
  • 1 tbsp butter (for brushing bread)
  • Fresh parsley, chopped (optional garnish)

👩‍🍳 Step-by-Step Instructions

Step 1: Cook the Beef

  1. Heat a large skillet over medium-high heat.
  2. Add ground beef and cook, breaking it up with a spoon, until browned.
  3. Drain excess grease if needed.

Step 2: Build the Flavor Base

  1. Add diced onion and bell pepper to the skillet.
  2. Cook for 3–4 minutes until softened.
  3. Stir in garlic and cook for 30 seconds until fragrant.

Step 3: Make the Sloppy Joe Sauce

  1. Reduce heat to medium.
  2. Add ketchup, tomato paste, Worcestershire sauce, brown sugar, mustard, paprika, chili powder, salt, pepper, and water/broth.
  3. Stir well and let simmer uncovered for 8–10 minutes until thick and rich.
  4. Taste and adjust seasoning if needed.

Step 4: Prepare the Bread

  1. Preheat oven to 375°F (190°C).
  2. Slice sub rolls lengthwise (do not cut all the way through).
  3. Brush lightly with butter.
  4. Place on a baking sheet and toast in oven for 5 minutes (this prevents soggy bread).

Step 5: Assemble the Subs

  1. Spoon generous amounts of sloppy joe mixture into each toasted roll.
  2. Top evenly with shredded cheese.

Step 6: Bake Until Melty

  1. Return subs to oven.
  2. Bake for 10–12 minutes, or until cheese is fully melted and bubbly.
  3. Optional: Broil for 1–2 minutes for golden cheese (watch closely).

Step 7: Garnish & Serve

  • Sprinkle with chopped parsley if desired.
  • Serve hot and gooey straight from the oven.
