Step-by-Step Instructions
Prepare the Sauce
In a small bowl, whisk together chicken broth, steak sauce, and Dijon mustard. Set aside. This mixture forms the flavorful base of your Sloppy Joe filling.
Brown the Beef
Heat a large skillet over medium-high heat. Add the ground beef and cook for about 7 to 8 minutes, breaking it up with a spoon until no pink remains. Drain excess fat, then remove the cooked beef and set it aside.
Sauté the Mushrooms and Onion
In the same skillet, melt the butter. Add chopped onions, sliced mushrooms, and Montreal steak seasoning. Cook for 7 to 8 minutes until the mushrooms are golden and the onions translucent. This step builds that deep, steakhouse-style flavor that sets this recipe apart.
Toast the Flour
Sprinkle the flour over the vegetables and stir for 1 to 2 minutes. This helps thicken the sauce later and gives a slightly nutty undertone.
Combine Everything
Return the cooked beef to the skillet. Pour in the prepared sauce mixture, stirring well. Reduce the heat to medium and let everything simmer for about 3 to 4 minutes until the filling thickens and becomes glossy.
Assemble the Sandwiches
Toast the burger buns lightly to prevent sogginess. Spoon a generous portion of the hot Sloppy Joe filling onto each bun base. Immediately sprinkle shredded cheddar cheese over the hot filling so it melts slightly. Top with the remaining bun halves and serve warm.
Tips for the Perfect Sloppy Joe
- Let the mushrooms brown properly: Don’t rush this step — golden mushrooms mean richer flavor.
- Toast the buns: Keeps them sturdy and adds a subtle crunch.
- Adjust thickness: If the mixture feels too thick, splash in a bit more broth. Too thin? Let it simmer longer.
- Shred cheese fresh: Pre-shredded cheese often contains starch and won’t melt as smoothly.
- Make it spicy: Add cayenne pepper, chili flakes, or a dash of hot sauce for heat.
Serving Suggestions
These Steakhouse Burger Sloppy Joes pair wonderfully with a variety of sides:
- Classic French fries or sweet potato fries for a diner-style combo.
- Crispy onion rings for extra crunch.
- Coleslaw or a green salad for a fresh, crisp balance.
- Pickles or grilled vegetables for tangy contrast.
You can also transform the leftovers into:
- Stuffed baked potatoes topped with extra cheese.
- Sloppy Joe nachos using tortilla chips.
- Loaded mac and cheese topping for an ultra-comforting twist.
Storage Tips
If you have leftovers, store the filling (without buns) in an airtight container in the refrigerator for up to 3 days. Reheat in a skillet over medium heat, adding a splash of broth or water to loosen it up.
To freeze, cool the mixture completely, portion it into freezer-safe bags, and freeze for up to 2 months. Thaw overnight in the fridge and reheat on the stovetop before serving.
Ingredient Substitutions
- Ground turkey or chicken: For a leaner version.
- Worcestershire sauce: Substitute for steak sauce in a pinch.
- Vegan cheese and plant-based meat: Works great for a dairy-free or vegetarian option.
- Bell peppers or zucchini: Replace mushrooms for a different veggie twist.
Why This Recipe Works

- Double the recipe for parties — it scales beautifully.
- For the ultimate finish, top with caramelized onions or a drizzle of aioli.
