Grilled Tuna - For the Carnivore Diet

Simple, high-heat grilled tuna basted with beef tallow and finished with flaky salt for a clean, carnivore-friendly meal.

This grilled tuna keeps flavors pure and protein high by relying on quality fish, salt, and animal fat. A quick dry brine draws surface moisture for better sear, while a tallow baste helps the fish release from the grate and adds richness.

Choose firm, 1-inch-thick steaks of yellowfin or ahi tuna. Pat them very dry, salt ahead to season through, and grill hot and fast. Aim for rare to medium-rare to keep the center tender and moist. If you prefer more doneness, simply add 30–60 seconds per side.

A final brush of warm tallow or butter after resting brings everything together. Serve as-is, or pair with a spoon of melted bone marrow or an egg yolk for extra fat if desired. If you don’t have an outdoor grill, a ripping-hot cast-iron skillet or grill pan works well.

Ingredients

Instructions

  1. Pat tuna steaks very dry with paper towels. Season all sides evenly with the salt and let rest at room temperature for 15–20 minutes.
  2. Preheat a grill to high heat (about 500–600°F). Scrape the grates clean, then oil them lightly with beef tallow.
  3. Brush the tuna lightly with melted tallow.
  4. Place the tuna on the hot grill. Sear for 60–90 seconds per side for rare, 90–120 seconds per side for medium-rare. Turn only once. Aim for about 110–115°F for rare or 120–125°F for medium-rare, or cook longer to preference.
  5. Transfer to a plate and rest 3–5 minutes. Brush with a little more melted tallow or butter and finish with a pinch of flaky salt if desired.
  6. Serve immediately. Optional carnivore add-ons: a spoon of melted bone marrow or a raw egg yolk on top.
