Introduction

If you love tuna but can’t stand it cold, these Keto Tuna Balls are the answer. They’re warm, cheesy, perfectly seasoned, and crisped up in the air fryer—making them a quick high-protein snack, appetizer, or even a light meal.

Step-by-Step Cooking Guide

Step 1 – Mix the base
Combine drained tuna, egg, shredded cheese, Parmesan, and seasonings in a bowl. Add finely chopped onions if you like extra flavor.

Step 2 – Form balls
Scoop mixture and roll into even-sized balls. Coat lightly in Parmesan to help crisp the outside.

Step 3 – Air fry
Place in the basket and cook at 400°F for 8–10 minutes, flipping halfway. If you prefer extra crispiness, extend cooking up to 10 minutes per side.

Ingredient Details & Substitution Tips

  • Tuna: White tuna gives mild flavor. You can also use albacore or even salmon.

  • Cheese: Colby works well, but cheddar, Monterey Jack, or mozzarella all make great swaps.

  • Parmesan: The shaker bottle variety works fine, but freshly grated Parmesan adds a stronger bite.

  • Seasonings: Garlic and onion powder are great basics. Add paprika, dill, or cayenne for variety.

Variations & Serving Suggestions

  • Cheesy Jalapeño Version: Add chopped jalapeños to the mix.

  • Italian Style: Mix in Italian seasoning and dip in marinara.

  • Buffalo Kick: Toss finished balls in buffalo sauce and serve with blue cheese dip.

  • Serving Ideas:

    • As an appetizer with dipping sauces.

    • On top of a salad for added protein.

    • Paired with roasted veggies for a keto-friendly meal.

Storage & Make-Ahead

  • Refrigeration: Store in an airtight container up to 3 days.

  • Reheating: Air fry again at 375°F for 3–4 minutes until warm.

  • Freezing: Freeze uncooked balls on a tray, then transfer to a bag. Cook from frozen, adding 2–3 minutes to air fryer time.

FAQs

Q: Can I bake these instead of air frying?
A: Yes—bake at 400°F for 15–18 minutes, flipping once.

Q: Can I use canned salmon instead of tuna?
A: Absolutely—it makes a slightly richer version.

Q: Do they hold together without breadcrumbs?
A: Yes—the cheese and egg act as binders, making this recipe fully keto.

Personal Note

These tuna balls are a lifesaver for me because I love tuna but can’t eat it cold. The air fryer makes them crispy on the outside while keeping the inside cheesy and soft. They’re quick, versatile, and always hit the spot when I need a warm, low-carb snack.
