How to Make Instant Pot Beef and Cheddar Sandwiches with Spicy Cheese Sauce Recipe
Step 1: Prepare the Beef
Start by layering thinly sliced beef in your Instant Pot. The thin slices are key for tender results in just minutes. Toss in the reduced-sodium beef broth, garlic powder, salt, and freshly ground black pepper. These simple seasonings work together to create a savory foundation full of flavor without overwhelming the natural beef taste.
Step 2: Pressure Cook the Beef
Seal the Instant Pot lid securely and select the High Pressure setting. Set the timer for 10 minutes, giving the beef a chance to cook to tender, juicy perfection. Once the cooking cycle finishes, let the pressure release naturally for 10 minutes to keep the beef succulent, then finish with a quick release to open the pot safely.
Step 3: Make the Spicy Cheese Sauce
While the beef is cooking, get started on the cheese sauce because that’s where the magic really happens. Melt the unsalted butter in a saucepan over medium heat, then sprinkle in the flour. Cooking the roux until it bubbles ensures a smooth, velvety base. Gradually whisk in the milk, stirring continuously until the sauce thickens beautifully. Stir in a tablespoon of hot sauce and salt for flavor balance. Then add your grated cheddar cheese in small batches, stirring until you have a perfectly creamy, spicy cheese sauce that’s guaranteed to dazzle your taste buds.
Step 4: Assemble Your Sandwiches
Butter and toast your onion hamburger buns to golden, crispy perfection. Pile each toasted bun generously with the tender, flavorful beef, then ladle over a hearty scoop of that irresistibly creamy, spicy cheese sauce. Serve these sandwiches piping hot for a meal that’s satisfying, indulgent, and just a little bit addictive.
How to Serve Instant Pot Beef and Cheddar Sandwiches with Spicy Cheese Sauce Recipe

Garnishes
For an extra layer of freshness and crunch, consider adding sliced pickles or a handful of fresh arugula on top of the beef before pouring over the cheese sauce. Red onion slices or a dash of smoked paprika can also add wonderful depth that complements the bold flavors perfectly.
Side Dishes
These sandwiches pair wonderfully with crispy sweet potato fries, a fresh green salad, or even a creamy coleslaw. The contrast in textures and flavors will round out the meal beautifully and keep things interesting on your plate.
Creative Ways to Present
Want to impress at your next gathering? Cut these sandwiches into smaller sliders for a party platter, or go open-faced and add a sprinkle of chopped chives or parsley for a vibrant pop of color. They’re just as delicious on rustic bread or within a sandwich wrap, making this recipe wonderfully versatile.
Make Ahead and Storage
Storing Leftovers
If you have leftovers, store the beef and cheese sauce separately in airtight containers in the refrigerator. This keeps the textures intact and ensures your sandwiches taste just as fresh when reheated the next day.
Freezing
This Instant Pot Beef and Cheddar Sandwiches with Spicy Cheese Sauce Recipe freezes well if you prepare in bulk. Freeze the cooked beef and cheese sauce individually in freezer-safe containers for up to three months, making meal prep a breeze on busy days.
Reheating
To reheat, thaw overnight in the fridge if frozen. Warm the beef gently in a skillet or microwave, then warm and stir the cheese sauce to return it to its creamy, smooth state. Toast your buns right before assembling for that perfect fresh-toasted bite every time.
FAQs
Can I use a different cut of beef?
Absolutely! While top round roast is ideal for tender slices, you can use other lean cuts like sirloin or chuck roast. Just make sure to slice them thinly for the best texture after cooking.
Is it possible to make the cheese sauce dairy-free?
Yes! Substitute the milk with a dairy-free alternative like almond or oat milk, and use a dairy-free cheese to make a delicious vegan-friendly spicy cheese sauce.
How spicy is the cheese sauce?
The hot sauce adds a gentle heat that complements the cheddar without overpowering it. Feel free to adjust the amount of hot sauce to suit your personal spice preference.
Can I use pre-shredded cheese?
While pre-shredded cheese works, freshly grated cheddar melts more smoothly and results in a creamier sauce with better flavor. If you have the time, freshly shredding cheese is worth the effort.
What can I serve instead of onion buns?
Any sturdy sandwich bun or roll will work. Pretzel buns, brioche, or even a crusty baguette can add a new twist to this classic sandwich while holding all the juicy, cheesy goodness.
Final Thoughts
There’s something so wonderfully satisfying about the combination of tender beef and a spicy, creamy cheese sauce nestled in toasted onion buns, and this Instant Pot Beef and Cheddar Sandwiches with Spicy Cheese Sauce Recipe hits that spot perfectly.

Ingredients
Beef
- 2 pounds boneless beef top round roast, thinly sliced
- 1/2 cup reduced-sodium beef broth
- 1/2 teaspoon garlic powder
- 1/2 teaspoon salt
- 1/2 teaspoon freshly ground black pepper
Buns
- 8 onion hamburger buns, buttered and toasted
Spicy Cheese Sauce
- 1/4 cup unsalted butter
- 1/4 cup all-purpose flour
- 2 cups milk
- 1 tablespoon hot sauce
- 1/2 teaspoon salt
- 3 cups grated cheddar cheese
Instructions
- Prepare the Beef: In the Instant Pot pressure cooking pot, combine the thinly sliced beef, reduced-sodium beef broth, garlic powder, salt, and freshly ground black pepper. Lock the lid securely in place to prepare for pressure cooking.
- Pressure Cook the Beef: Select the High Pressure setting on the Instant Pot and set the cook time for 10 minutes. When the cooking finishes, turn off the pressure cooker and allow the pressure to release naturally for 10 minutes, then carefully perform a quick release. Once the valve drops, remove the lid carefully to access the tender cooked beef.
- Make the Cheese Sauce: While the beef cooks, melt the unsalted butter in a medium saucepan over medium heat. Sprinkle in the all-purpose flour and cook, stirring frequently, until it begins bubbling and forms a roux. Gradually whisk in the milk in small increments to avoid lumps until the sauce is smooth and thickened. Stir in the hot sauce and salt, then add the grated cheddar cheese gradually, stirring continuously until fully melted and the sauce is creamy and smooth. Remove from heat.
- Assemble and Serve: Butter and toast the onion hamburger buns. To serve, place a generous portion of the cooked beef on each toasted bun and ladle the spicy cheddar cheese sauce over the meat. Serve immediately while warm for the best flavor and texture.
Notes
- Thin slicing the beef helps it cook quickly and become tender in the Instant Pot.
- Allowing natural pressure release improves meat tenderness.
- The cheese sauce can be adjusted in spice level by varying the hot sauce amount.
- For extra flavor, consider adding caramelized onions inside the sandwiches.
- Use reduced-sodium broth to control saltiness, as the cheese is already salty.
