- Whole Milk & Crème Fraîche: Both add creaminess and just a hint of tang, giving the sauce that professional bistro flair.

How to Make Grilled Cheesesteak Sandwich
Step 1: Grill the Sirloin to Perfection
Get your grill ripping hot with a two-zone setup (that’s a direct heat side for searing, and an indirect side for gentle roasting). Score the fat cap of the Coulotte roast in a crisscross pattern—this helps render more fat for a juicy bite. Rub it all over with olive oil and SPG seasoning, then sear each side over the hottest part of the grill for a golden crust, about 5 minutes per side with the lid closed. Then move to indirect heat and cook covered until the center hits 140°F. Rest for 10 minutes before slicing; this is non-negotiable for juicy, tender beef!
Step 2: Sauté the Vegetables
Meanwhile, heat a splash of olive oil in a cast-iron or heavy skillet over medium heat. Start by browning the mushrooms—let them sit undisturbed so they develop that gorgeous caramelization, about 8–10 minutes. Remove, then add a bit more oil, toss in the onions and green bell pepper, and cook until soft, sweet, and just starting to brown around the edges. Set aside with the mushrooms, ready for sandwich glory.
Step 3: Make the Luscious Cheese Sauce
In a medium saucepan, gently melt butter, then whisk in flour to create a blond roux. Cook for two minutes, then slowly whisk in the milk—don’t rush, or risk lumps! Let it thicken for about four minutes at a gentle simmer, then stir in crème fraîche, Dijon, salt, and pepper until silky. Off the heat, add cheddar cheese and stir until glossy and smooth. Congratulations, you’ve just made the sandwich of your dreams even dreamier!
Step 4: Toast and Build the Sandwich
Slice the rested steak thinly and against the grain—this makes all the difference in tenderness! Toast the hoagie rolls cut-side down on the grill (or in a buttered skillet) until golden and crisp. Layer on generous slices of beef, pile on those sweet and savory veggies, and give everything a generous pour of the cheese sauce. Top with pickled hot peppers, if you like a zingy pop of flavor, then dig in while it’s hot and melty!
Pro Tips for Making Grilled Cheesesteak Sandwich
- Slice Against the Grain: Always cut your steak perpendicular to the lines in the meat—this gives you melt-in-the-mouth tenderness in every bite.
- Don’t Rush the Veggies: Let mushrooms, onions, and peppers caramelize for deep flavor—resist stirring too often and give them some space!
- Perfect Cheese Sauce Texture: Be patient when whisking in the milk and cheese; slow, steady stirring ensures your sauce stays creamy and lump-free.
- Use Fresh Rolls: Slightly stale bread turns dry on the grill, so grab soft, fresh hoagies for the best texture and flavor.
How to Serve Grilled Cheesesteak Sandwich
Garnishes
Brighten things up with a handful of fresh chopped parsley or green onions scattered on top of your Grilled Cheesesteak Sandwich. If you’re feeling adventurous, a sprinkle of flaky sea salt or even a drizzle of hot sauce makes every element pop.
Side Dishes
Pair your sandwich with golden, crispy fries, tangy coleslaw, or a simple green salad to keep things classic and fresh. For something a bit different, try pickle spears, potato chips, or even a homemade roasted vegetable medley on the side.
Creative Ways to Present
Serve up mini versions slider-style for party apps, or wrap your Grilled Cheesesteak Sandwich in parchment for a picnic. You can even layer the ingredients open-faced on toasted baguette slices for a fun, shareable twist—so cute and perfect for game day spreads!
Make Ahead and Storage
Storing Leftovers
If you have leftovers, keep the beef, veggies, cheese sauce, and rolls separate in airtight containers—the sandwich is best assembled fresh! Refrigerated, each component keeps well for up to 3 days.
Freezing
The cooked steak and sautéed veggies freeze beautifully—cool completely, then store in freezer bags for up to 2 months. Cheese sauce can be frozen, but may require gentle reheating and whisking to bring back its creaminess.
Reheating
To reheat, gently warm the beef and veggies in a skillet until heated through. For the cheese sauce, use low heat on the stove and whisk occasionally, adding a splash of milk if it’s too thick. Assemble the sandwich on freshly toasted rolls for that irresistible “just made” flavor!
FAQs
-
Can I use a different cut of beef for this Grilled Cheesesteak Sandwich?
Absolutely! While sirloin Coulotte is juicy and tender, ribeye, flank steak, or even thinly sliced skirt steak work wonderfully. Key tip: slice against the grain for maximum tenderness, no matter your cut.
-
Is it necessary to make the cheese sauce from scratch?
Homemade cheese sauce is what makes this Grilled Cheesesteak Sandwich truly special—it’s rich, silky, and customizable. If you’re short on time, you can substitute with your favorite melting cheese slices, but you’ll definitely notice the upgrade!
-
Can I prepare any part of this sandwich ahead of time?
Yes! You can grill and slice the beef, sauté the veggies, and even make the cheese sauce a day in advance. Store everything separately in the fridge, then assemble and reheat when you’re ready to eat.
-
How do I keep the sandwich from getting soggy?
To prevent sogginess, toast your hoagie rolls right before assembling, layer the beef and veggies first, and spoon on the cheese sauce just before serving. Keeping the layers structured helps everything hold up beautifully!
