Side Dish10 min2599 cal / serving

Imagine the best parts of a sizzling fajita platter combined with the comfort of crispy potato wedges. That’s exactly what you get with this loaded dish. Potatoes are roasted alongside green pepper and red onion, all seasoned with a bold fajita spice blend. While they crisp up, you’ll whip up a quick garlic mayo that adds a creamy, tangy kick.

Once the wedges are tender and golden, they’re topped with a blend of cheddar and pepper jack cheese and returned to the oven until bubbly and melty. A final garnish of diced tomato and a drizzle of garlic mayo makes every bite irresistible. Serve straight from the pan for a fun, shareable meal that’s perfect for weeknights or game day.

Instructions

  1. Preheat oven to 425°F (220°C). Cut potatoes into 1/2-inch thick wedges. Cut green pepper into thin strips. Peel and slice red onion into thin wedges. Mince garlic. Dice tomato.
  2. In a large bowl, toss potato wedges, green pepper strips and red onion with olive oil, fajita spice blend, salt and black pepper until evenly coated.
  3. Spread vegetables in a single layer on a baking sheet. Roast for 25-30 minutes, flipping halfway, until potatoes are golden and tender.
  4. Meanwhile, in a small bowl, combine mayonnaise, minced garlic and garlic powder. Season with salt and pepper to taste. Set aside.
  5. Once vegetables are roasted, remove from oven. Sprinkle cheddar and pepper jack cheeses evenly over the top. Return to oven for 3-5 minutes, until cheese is melted and bubbly.
  6. Drizzle garlic mayo over the cheesy wedges, then top with diced tomato. Serve immediately straight from the pan.

Recipe Tips

For extra crispy wedges, soak cut potatoes in cold water for 30 minutes, then pat dry before tossing with oil and spices.

If you prefer less heat, use monterey jack instead of pepper jack or reduce the fajita spice.

Leftover garlic mayo keeps in the fridge for up to 3 days and is great on sandwiches or as a dip.

FAQ

Can I use sweet potatoes instead?

Yes, sweet potatoes work well. Adjust roasting time as needed since they may cook faster.

What can I substitute for fajita spice blend?

Mix 1 teaspoon chili powder, 1/2 teaspoon cumin, 1/2 teaspoon paprika, 1/4 teaspoon garlic powder and a pinch of cayenne.

Can I make this dish ahead of time?

The wedges are best served fresh, but you can prep the vegetables and garlic mayo a day ahead. Assemble and bake just before serving.
