🛒 Ingredients Checklist

  • Ground beef (lean preferred)

  • Chicken broth

  • Steak sauce

  • Dijon mustard

  • Mushrooms (thinly sliced)

  • Onion (coarsely chopped)

  • Montreal steak seasoning

  • All-purpose flour (for thickening)

  • Butter

  • Cheddar cheese (shredded, sharp recommended)

  • Burger buns or sandwich rolls (for serving)

👩‍🍳 Instructions

  1. Brown the Beef
    In a large skillet over medium heat, cook ground beef until browned and no longer pink. Drain excess fat if necessary and set aside.

  2. Sauté the Veggies
    In the same skillet, melt butter. Add onions and mushrooms. Cook for 5–7 minutes until mushrooms are browned and onions are soft.

  3. Add Flour & Seasoning
    Sprinkle flour and steak seasoning over the cooked vegetables. Stir and cook for 1–2 minutes to get rid of the raw flour taste.

  4. Deglaze & Build the Sauce
    Pour in chicken broth, steak sauce, and Dijon mustard. Stir to combine, scraping up any browned bits from the bottom of the pan.

  5. Simmer & Combine
    Return the beef to the skillet and stir everything together. Simmer for 5–10 minutes until the mixture thickens into a rich, spoonable filling.

  6. Melt Cheese In
    Stir in shredded cheddar until melted and creamy. Or, spoon the filling onto buns and top each with cheese, letting it melt from the heat.

  7. Serve Hot
    Pile the mixture onto toasted buns. Serve with pickles, chips, or a crisp salad.

🔎 Recipe Notes

  • Cheddar Tip: Use freshly shredded sharp cheddar for the best melt and flavor.

  • Don’t skip the Dijon! It adds a tangy bite that balances the richness.

  • Make it spicy: Add a few dashes of hot sauce or a pinch of cayenne with the steak seasoning.

👣 Step-by-Step Guide

Building Layers of Flavor

Start by browning the beef for that deep, savory base. Then sauté mushrooms and onions in butter until golden—this gives your sloppy joes a steakhouse-level depth.

Tip: Browning the mushrooms well adds a big umami boost to the final flavor.

Thickening the Sauce

Flour helps create a velvety, clingy sauce that stays put in your sandwich (no more soggy buns!). Simmering helps bring all the flavors together.

🥄 Ingredient Tips & Substitutions

Ingredient Highlights:

  • Montreal Steak Seasoning: Packed with bold spices—adds instant complexity.

  • Mushrooms: White or cremini mushrooms both work well.

  • Steak Sauce: Choose one with a slightly tangy, smoky profile (like A1 or similar).

Substitutions:

  • No Dijon? Use yellow mustard for a milder taste.

  • No steak seasoning? Mix coarse salt, cracked black pepper, garlic powder, and paprika.

  • Vegetarian version: Use meatless ground and veggie broth.

🍽 Serving & Pairing Ideas

Serve With:

  • Toasted brioche or pretzel buns

  • Garlic fries or kettle chips

  • A green salad or creamy coleslaw

Drink Pairings:

  • Iced tea, cold beer, or a bold red wine (like zinfandel)

  • For kids: root beer or lemonade

Make it a party platter with slider buns and let everyone build their own!

🧊 Storage & Make-Ahead Tips

  • Fridge: Store leftover filling in an airtight container for up to 4 days.

  • Freezer: Freeze cooled filling in zip-top bags for up to 3 months. Thaw overnight in the fridge before reheating.

  • Reheat: Warm on the stovetop or microwave with a splash of broth if needed.

❓ FAQ

Q: Can I make this ahead?

Q: Can I make it dairy-free?
A: Omit the cheese or use a plant-based shredded cheese alternative.

Q: What kind of steak sauce should I use?
A: Any bold-flavored steak sauce works—A1, HP Sauce, or even a smoky BBQ sauce for a twist.
