  • 1 small onion, finely diced
  • 1 green bell pepper, finely diced (optional but recommended)
  • 2 cloves garlic, minced
  • ¾ cup ketchup

  • 1½ tbsp brown sugar
  • 1 tsp yellow mustard
  • 1 tsp paprika
  • ½ tsp chili powder (optional)

👩‍🍳 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

  2. Top evenly with shredded cheese.

Step 6: Bake Until Melty

  1. Return subs to oven.
