Ingredients

Servings6

1/2 lb (225g) lean ground beef (90% lean)
1 cup finely chopped cauliflower florets (about 100g)
1/4 cup finely diced onion
1 clove garlic, minced
1/4 cup grated Parmesan cheese
1 large egg, lightly beaten
1/4 cup almond flour
1 teaspoon Worcestershire sauce
1/2 teaspoon smoked paprika
1/2 teaspoon kosher salt
1/4 teaspoon freshly ground black pepper
6 mini slider buns (or low-carb buns for keto option)
Cooking spray (preferably avocado or olive oil)
1/3 cup mayonnaise
2 teaspoons prepared horseradish (adjust to taste)
1 teaspoon fresh lemon juice
1/4 teaspoon garlic powder
Salt and pepper to taste
Lettuce leaves, as needed for serving
Thinly sliced tomatoes, as needed for serving
Pickles, as needed for serving

Instructions

Preheat your air fryer to 375°F (190°C) for 5 minutes.
In a large bowl, combine ground beef, finely chopped cauliflower, diced onion, minced garlic, grated Parmesan, beaten egg, almond flour, Worcestershire sauce, smoked paprika, salt, and pepper.
Mix gently but thoroughly using your hands or a spatula until all ingredients are well incorporated, being careful not to overwork the meat.
Divide the mixture into 6 equal portions and shape each into a compact patty about 2.5 inches (6 cm) wide, slightly smaller than the slider buns as they will shrink slightly during cooking.
Lightly spray the air fryer basket with cooking spray to prevent sticking.
Arrange the patties in a single layer without overcrowding; cook in batches if needed depending on your air fryer’s capacity.
Air fry the patties at 375°F (190°C) for 10-12 minutes, flipping halfway through (around 6 minutes), until fully cooked (internal temperature 160°F/71°C) and the exterior is crisp and golden.
While patties cook, whisk together mayonnaise, horseradish, lemon juice, garlic powder, salt, and pepper in a small bowl for the horseradish aioli. Adjust horseradish amount to taste.
Remove cooked patties and let them rest for 2 minutes.
Optionally, toast slider buns in the air fryer for 1-2 minutes to enhance texture.
Assemble each slider by spreading horseradish aioli on the bottom bun, layering with a beef-cauliflower patty, lettuce, tomato slices, and pickles if using, then topping with the bun.
Serve immediately for the best crispiness and enjoy these wholesome sliders packed with flavor and nutrition.

Recipe guidance

Crispiness Control

Pat the lean ground beef dry, avoid crowding, and use only a light coat of oil or sauce before cooking. Add wet sauces near the end when you want the outside to stay crisp.

Storage

Store leftover Air Fryer Beef and Cauliflower Patty Sliders with Horseradish Aioli in an airtight container in the refrigerator for up to 3 days. Cool the food before sealing so excess steam does not soften the texture.
