6
- 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
- Thinly sliced tomatoes
- Pickles
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, family-friendly sliders packed with flavor and nutrition.

Air Fryer Model Notes
This Air Fryer Beef and Cauliflower Patty Slider recipe is optimized for air fryer cooking to achieve crispy, juicy patties with minimal fuss. Cooking results may vary depending on your air fryer model and features.
- Basket Size and Capacity: Smaller air fryers might require cooking in multiple batches to avoid overcrowding, ensuring even crisping and cooking. Larger baskets allow more airflow and better browning when patties are spaced adequately.
- Temperature Accuracy: Some air fryer models may run hotter or cooler than their settings indicate. Check patties a few minutes earlier or add cooking time as needed when cooking at 375°F (190°C).
- Air Fryer Type: Basket-style air fryers provide great airflow around patties for optimal crisping. Oven-style or toaster oven air fryers may require more frequent flipping or rotating for even cooking.
- Flip and Accessibility: Removable baskets and non-stick coatings make flipping easier. Some models offer shake or rotate functions to assist with uniform browning.
- Preheating: Preheating the air fryer for 5 minutes at 375°F is recommended to ensure a crisp crust on your sliders. If your model lacks preheat, run it empty for a few minutes before adding patties.
Adjust cook times and techniques to suit your specific air fryer model for perfectly cooked, crispy sliders every time.
Crispiness Control
Customize the crispiness of your Air Fryer Beef and Cauliflower Patty Sliders with these tips, balancing a crisp exterior with juicy, tender interiors — perfect for low-carb, family-friendly meals.
- Extra Crispy: After the initial 10-12 minutes at 375°F (190°C), cook for an additional 1-2 minutes without flipping to firm up the crust. Avoid overcrowding to ensure crispness.
- Moderate Crispiness: The standard cooking time with one flip produces a golden crust and succulent center, ideal for kids and family preferences.
- Softer Texture: Reduce cook time by 1-2 minutes or lower temperature to 360°F (182°C) to prioritize juiciness over crustiness.
- Additional Tip: Lightly spray patties with avocado or olive oil cooking spray before air frying to encourage even browning without adding excess fat. Toast slider buns in the air fryer for 1-2 minutes to complement the patties.
Use your air fryer’s airflow to achieve a customized crispness that suits your taste buds.
