Hearty Smash Burger Fries

Figuring out a satisfying dinner when you’re short on time and energy can feel like an impossible task. Between juggling after-school activities, work deadlines, and the usual evening rush, sometimes even ordering takeout seems too complicated. That’s exactly why these smash burger fries have become my family’s favorite weeknight solution.

These loaded fries give you all the flavors of a classic smash burger but come together in one pan, making them perfect for those nights when you want something tasty without the fuss. Plus, they’re easy to customize with whatever toppings your family loves most.

What Kind of Ground Beef Should I Use?

For smash burgers, the fat content of your ground beef really matters. An 80/20 blend (that’s 80% lean meat to 20% fat) is ideal since it gives you the perfect amount of fat to create those crispy, lacy edges that make smash burgers so special. While you could use leaner ground beef like 90/10, you’ll miss out on some of that classic smash burger flavor and texture. Ground chuck is usually your best bet at the grocery store, but any fresh ground beef with the right fat content will work well. Just make sure your meat is very cold when you start cooking – this helps create those delicious crispy edges when you smash it on the hot cooking surface.

Options for Substitutions

This loaded fries recipe is pretty adaptable – here are some easy swaps you can make:

• Frozen french fries: While frozen fries are super convenient, you can use fresh-cut fries, sweet potato fries, or even tater tots. Just make sure they’re nice and crispy before adding toppings.
• White cheddar: Any good melting cheese works here – try yellow cheddar, Monterey Jack, or even American cheese. For the sauce, just make sure to grate it yourself as pre-shredded cheese doesn’t melt as smoothly.
• Ground beef: Feel free to swap in ground turkey or chicken for a lighter option. You could even use plant-based ground meat alternatives – just season well!
• Milk: For the cheese sauce, you can use any milk you have on hand – whole, 2%, or even half-and-half for extra richness.
• Dill relish: Sweet relish works too in the sauce, or finely chopped pickles if that’s what you have.
• Smoked paprika: Regular paprika works fine, or try a pinch of chipotle powder for a different smoky kick.
• Apple cider vinegar: White vinegar or rice vinegar can step in – you just need that bit of tang in the sauce.

Watch Out for These Mistakes While Cooking

The biggest challenge when making smash burger fries is getting the right texture for your burger patties – pressing them too gently won’t create those crispy, lacy edges that make smash burgers special, so use firm pressure with your spatula and press down for about 10 seconds when the meat hits the hot pan.

When making the cheese sauce, rushing the process can lead to a grainy texture, so be sure to melt the butter and flour mixture (roux) over medium-low heat for at least 1-2 minutes before slowly adding your milk, and always use freshly grated cheese since pre-shredded varieties contain anti-caking agents that can make your sauce clumpy.

For the crispiest fries, avoid overcrowding your baking sheet – give each fry enough space to get golden and crunchy, and don’t forget to flip them halfway through cooking.

The special sauce can become too thin if you don’t drain excess liquid from your grated onion, so after grating, press the onion in a paper towel to remove extra moisture before mixing it with the other sauce ingredients.

What to Serve With Smash Burger Fries?

Since smash burger fries are already a hearty combo of burger toppings and french fries with cheese sauce, you’ll want to keep the sides simple and fresh. A crunchy coleslaw made with a tangy vinegar dressing can cut through the richness of the dish while adding a nice contrast in texture. For something green, a simple side salad with crisp lettuce, tomatoes, and red onions works great – just keep the dressing light since the fries already come with a creamy sauce. If you’re feeding a crowd, some pickle spears or crispy onion rings on the side let people customize their plates, though the dish is totally satisfying on its own!

Storage Instructions

Keep Fresh: These loaded fries are best enjoyed right away while they’re hot and crispy! If you have leftovers, place them in an airtight container in the fridge for up to 2 days. The special sauce can be stored separately in the fridge for up to a week – it’s great to have on hand for other sandwiches too!

Make Ahead: Want to prep ahead? Mix up the special sauce a day or two before – it actually tastes even better after the flavors have time to mingle. You can also grate the cheese and prep your toppings in advance, storing them separately in the fridge until you’re ready to assemble.

Revive: To bring leftover smash burger fries back to life, spread them on a baking sheet and pop them in a 375°F oven for about 10 minutes. The fries will crisp up nicely, and you can add fresh cheese on top during the last few minutes. Add your cold toppings after heating.

Ingredients

For the fries and burger topping:

• Thin jalapeño slices, for garnish (for a spicy kick)
• Pickles, whole or diced, for garnish
• 1 package frozen crispy fries
• Kosher salt and pepper, to taste
• 1/2 lb ground beef (80/20 lean preferred for juiciness)

For the cheese sauce:

• 2 tbsp all-purpose flour (I always use King Arthur all-purpose flour)
• 1 cup milk
• 2 tbsp unsalted butter
• 2 1/2 cups grated white cheddar cheese

For the special sauce:

• 2 tbsp freshly shredded onion
• 1 cup mayonnaise (I prefer Hellmann’s mayonnaise)
• 1 tsp apple cider vinegar
• 1/2 tsp smoked paprika
• 2 tbsp ketchup
• 2 tbsp dill relish
• 1 tsp honey

Step 1: Bake the Fries

• 1 (26 oz) package frozen crispy fries

Preheat your oven to 450°F.

Arrange the frozen crispy fries in a single layer on a baking sheet.

Bake for 20 to 25 minutes, flipping once during cooking for even crispiness.

If the fries’ package instructions recommend a different temperature or time, follow those for optimal results, but I prefer 450°F for that extra crunch.

Step 2: Cook the Smashburger Ground Beef

• 1/2 lb ground beef
• kosher salt and pepper, to taste

While the fries are baking, season the ground beef thoroughly with kosher salt and pepper.

Heat a skillet, preferably cast iron, over medium-high heat and add a bit of butter or oil if desired (not listed in your ingredients, but a small amount can enhance browning).

Divide the ground beef into 6 even pieces.

Once the skillet is hot, press each portion into the skillet using a sturdy spatula or jar to create thin patties.

Cook until the underside is browned, then flip and cook the other side for 1-2 more minutes until browned.

Turn off the heat once done.

Step 3: Assemble and Bake the Smashburger Fries

• baked fries (from Step 1)
• cooked ground beef patties (from Step 2)

Once the fries are crisp and the burger patties are cooked, arrange the baked fries on an oven-safe platter or leave them on the baking sheet.

Drizzle with cheese sauce if you’ve made it, then break up the cooked burger patties from Step 2 and distribute them evenly over the fries.

Drizzle more cheese sauce on top.

Return the assembly to the oven for 5 to 10 minutes, just until everything is hot and the flavors meld.

Step 4: Garnish and Serve

• pickles, whole or diced, for garnish
• thin jalapeño slices, for garnish

Remove the assembled fries from the oven.

Drizzle with thousand island dressing if you like, then top with pickles and thin jalapeño slices.

You can finish with any other toppings you love for extra flavor and texture.

I like a generous helping of pickles for a tangy crunch right before serving!
