Steakhouse Burger Sloppy Joes pair the comfort of a nostalgic sandwich with a deep savory kick from mushrooms and steakhouse-style sauce all blanketed with melty cheddar cheese and piled high on tender buns. This craveworthy twist is my go-to when I want real burger flavors but something saucier and family-friendly for busy weeknights. It is hearty meets handheld in the best way.
I first made these steakhouse sloppy joes at a last-minute gathering when burgers felt too formal and messy. Everyone raved about the saucy goodness and I have kept them in my dinner rotation ever since.
Ingredients
- Ground beef: brings hearty protein and traditional sloppy joe bite so look for eighty five percent lean for best moisture
- Mushrooms: add earthy savor and soak up sauce beautifully select firm cremini or white button mushrooms without bruising
- White onion: coarsely chopped builds depth and sweetness pick a firm small onion and avoid sprouting bulbs
- Chicken broth: forms the sauce base and adds umami opt for low sodium to control seasoning
- Steak sauce: delivers that steakhouse zing use your favorite brand but I like one with bold vinegar notes
- Dijon mustard: brightens the sauce and cuts the richness choose smooth Dijon over whole grain
- Butter: adds luscious richness and helps brown mushrooms use real butter for best results
- Montreal steak seasoning: gives smoky peppery backbone read the ingredients and use a fresh blend for full flavor
- All purpose flour: thickens the sloppy joe filling make sure it is unbleached for less processed taste
- Burger buns: are the all important cradle opt for soft yet sturdy ones that toast well
- Sharp cheddar cheese: turns gooey and sharp over the hot filling always shred it fresh for max melt
Step-by-Step Instructions
- Make the Sauce:
- In a medium bowl whisk chicken broth steak sauce and Dijon mustard until combined. Set aside to allow the flavors to marry.
- Brown the Beef:
- Heat a large twelve inch skillet over medium high. Add ground beef and cook for seven to eight minutes breaking it up with a spoon until no pink remains. Drain off extra fat for balanced flavor. Remove beef and set aside.
- Brown Mushrooms and Onion:
- Add butter to the same skillet along with mushrooms onion and steak seasoning. Let these cook together for about seven to eight minutes stirring now and then until the onions turn translucent and mushrooms are deeply browned. This step brings out all the savor in your dish.
- Toast the Flour:
- Sprinkle flour evenly over the vegetables. Stir and cook for one to two minutes until the flour darkens slightly and releases a nutty aroma. Do not rush as this builds the thick wheelhouse sauce.
- Combine and Simmer:
- Return the cooked beef to the skillet. Pour in the prepared broth and sauce mixture. Stir thoroughly and simmer on medium for three to four minutes until everything thickens into glorious sloppy joe filling.
- Assemble and Serve:
- Spoon about one third cup of hot steakhouse beef mixture onto the base of each bun. Top with a generous tablespoon of shredded cheddar so it melts right in place. Add the bun top and serve immediately while piping hot.

My favorite part is how the mushrooms carry all the steakhouse seasonings. My family laughs remembering how my youngest used to pick out mushrooms until this recipe renewed her love for them. Now she is the first to ask if there are leftovers for tomorrow.
Storage Tips
Store any leftover sloppy joe filling in an airtight container in the fridge for up to three days. To reheat scoop into a skillet with a splash of broth for moisture and gently warm over low heat. Filled buns freeze surprisingly well too for quick future dinners just thaw and reheat in foil until steaming.
Ingredient Substitutions
Feel free to swap ground turkey for beef if you want something lighter. A dash of Worcestershire can replace steak sauce if you are out. If mushrooms are not your thing try bell pepper or even zucchini for a subtle veggie swap. For those avoiding dairy use a vegan cheese shreds substitute that melts well.
Serving Suggestions
These steakhouse sloppy joes are amazing as is but you can dress them up with crispy onion rings a side of sweet potato fries or a big dill pickle. Sometimes I serve them with slaw for extra crunch or lay down a bed of arugula on the bottom bun for a peppery bite.
