This weeknight winner brings together the zesty flair of fajitas with the pure comfort of a burger, all in under 30 minutes. The result? A symphony of flavors: sweet, charred bell peppers and onions, spicy chipotle sauce, rich beef, and creamy cheese, with fresh toppings for good measure. Even better, the process is quick, unfussy, and endlessly customizable—ideal for busy evenings or a casual cookout.

Ingredients You’ll Need

• Ground Beef Burger Patties: The flavorful, juicy base—look for 91% lean for a lighter burger, or choose your favorite ground meat. Tip: Store-bought frozen patties work just as well as homemade!
• Burger Buns: Soft, sturdy buns hold all those juicy toppings without falling apart. Brioche or classic white buns are both excellent.
• White Cheddar Cheese: Melts beautifully, lending a creamy, sharp tang that pairs perfectly with the spicy peppers.
• Red and Green Bell Peppers: Bring color, crunch, and natural sweetness when sautéed—your secret to that quintessential fajita flavor.
• Yellow Onion: Sliced thin and sautéed with the peppers, adding depth and a hint of sweetness.
• Chipotle Peppers in Adobo Sauce: Smoky, spicy, and absolutely essential; the sauce coats the veggies for Tex-Mex pizzazz. Adjust the amount to control the heat!
• Water: Helps create a saucy topping for the burgers—don’t skip this step for best texture.
• Lettuce (Optional): Adds crisp freshness to contrast the hearty, spicy toppings.
• Avocado (Optional): Creamy avocado perfectly tames the heat and ups the burger’s lusciousness.

Note: For less spice, use just 1/4 to 1/2 a can of chipotle peppers; the full can brings a serious kick!

Variations

• Swap the Protein: Use ground turkey, chicken, or even plant-based patties for a different twist—just adjust cooking times as needed.
• Cheese Choices: Pepper jack lends extra heat, while Monterey Jack is a milder, gooier option.
• Veggie Boost: Add sautéed mushrooms or zucchini with the peppers for an extra veggie punch.
• Low-Carb: Skip the bun and serve over a salad, or use lettuce wraps for a lighter meal.
• Kid-Friendly: Skip or reduce the chipotles and offer the peppers plain for a milder, family-friendly version.
• Toppings Galore: Pickled jalapeños, fresh salsa, or a dollop of sour cream make excellent final touches.

How to Make Fajita Burgers

Step 1: Prep the Veggies

Thinly slice your bell peppers and onion. Prepping everything ahead makes assembly a breeze!

Step 2: Sauté Bell Peppers and Onions

Heat a sauté pan over medium-low. Spray it with a little cooking spray. Add your sliced onions and bell peppers, stirring occasionally until they’re tender and sweet—about 10 minutes.

Step 3: Add Chipotles

While veggies cook, open your can of chipotle peppers in adobo. Chop the large peppers finely if you like extra heat. Once the peppers and onions are soft, stir in the chopped chipotles and their sauce. Pour in 1/4 cup water, reduce to a simmer, and let it gently bubble while you finish the burgers. This step is what delivers that signature smoky-spicy flair—don’t rush it!

Step 4: Cook Burger Patties

Meanwhile, grill or pan-fry your burger patties to your preferred doneness. Pre-formed frozen patties are a lifesaver on busy nights, but fresh is fantastic too.

Step 5: Melt the Cheese

In the last minute of cooking, place a slice of white cheddar on each patty and cover briefly to melt.

Step 6: Assemble the Burgers

Now the fun part: Build your masterpiece! Start with the bottom bun, add lettuce (if using), then the cheesy burger patty. Pile on a generous spoonful of the chipotle pepper mixture—aim for about 75g if you like to be precise. Layer avocado slices if you’re feeling fancy, then finish with the top bun.

Step 7: Enjoy!

Take a moment for that first, glorious bite!

How to Serve

You’ll want to keep the sides simple, so these flavorful burgers shine! Serve with crispy oven fries, a fresh corn salad, or tortilla chips with salsa. For a lighter meal, offer a green salad on the side. Add lime wedges for squeezing over the top—trust me, it brightens up every bite! If you’re hosting, set up a topping bar with chopped cilantro, pickled onions, and extra avocado so everyone can build their ultimate burger.

Make Ahead and Storage

Storing Leftovers

Any leftover peppers and onions keep beautifully in an airtight container in the fridge for up to 4 days. Store burger patties and buns separately to keep everything fresh.

Freezing

The cooked peppers and onions freeze well (up to 2 months). Burger patties can also be frozen individually; thaw in the fridge before reheating.

Reheating

Reheat veggies gently in a skillet until hot, or microwave in short bursts. Warm burger patties in a covered skillet or in the microwave. Always assemble fresh for best taste and texture.
