Salt is the only universally accepted seasoning on the carnivore diet, but beyond that, what you can use depends on how strictly you follow it. Most carnivore followers use salt freely and add animal-based flavor boosters like butter and bone marrow. Some also include black pepper, garlic powder, or other simple spices, while the strictest version of the diet limits you to salt and water alone.
Salt Is the Foundation
Every version of the carnivore diet allows salt, and most practitioners consider it essential rather than optional. When you stop eating processed foods, your sodium intake drops significantly. At the same time, low-carb eating causes your kidneys to excrete more sodium than usual, which can lead to headaches, fatigue, and muscle cramps if you don’t compensate.
The most commonly recommended options are Himalayan pink salt and unrefined sea salt, both of which contain trace minerals like potassium, magnesium, and calcium alongside sodium. Iodized table salt is also worth considering. Since the carnivore diet eliminates plant-based iodine sources like seaweed and iodized bread, iodized salt can help prevent a deficiency that would otherwise be easy to develop. Many carnivore dieters keep both types on hand, using sea salt or pink salt for cooking and iodized salt at the table.
One thing to watch: some commercial salts contain anti-caking agents like sodium aluminosilicate or calcium silicate. These are added in such small amounts that the FDA permits manufacturers to leave them off the label entirely. If avoiding all additives matters to you, look for salts labeled “unrefined” or check the ingredients for a single entry: salt.
Strictness Levels Change the Rules
The carnivore diet isn’t one set of rules. It exists on a spectrum, and where you land determines which seasonings are on the table.
The Lion Diet is the most restrictive version. Described by its proponents as an elimination protocol for gut issues, it allows only ruminant meat (beef, lamb, bison, venison), salt, and water. No spices, no pepper, no butter, no eggs. The idea is to strip your diet down to the bare minimum, then slowly reintroduce foods to identify what triggers symptoms. If you’re following this version, salt is your only seasoning, full stop.
Standard carnivore is what most people mean when they talk about the diet. It includes all animal foods: red meat, poultry, fish, eggs, organ meats, bone marrow, and small amounts of low-lactose dairy like butter and hard cheese. Salt is a given, and most followers also allow black pepper. Beyond that, opinions split. Some people use simple single-ingredient spices like garlic powder, onion powder, or paprika, reasoning that the tiny amounts used in seasoning don’t meaningfully introduce plant compounds. Others draw a hard line at anything that isn’t animal-derived.
Relaxed or “animal-based” carnivore is the most flexible tier. Followers here typically allow all spices and herbs, along with certain condiments, as long as they avoid sugar, seed oils, and processed ingredients. This version treats the diet more as a framework than a strict protocol.
Animal-Based Ways to Add Flavor
Before reaching for the spice rack, it’s worth exploring how much flavor you can get from animal sources alone. Many long-term carnivore dieters say they stopped missing seasonings once they learned to cook meat well.
Butter, especially from grass-fed sources, is one of the most popular flavor additions. A pat of butter melting over a hot steak adds richness that replaces the role most seasonings play. Bone marrow, roasted until soft, has a deep, savory flavor that works as both a side dish and a natural fat for cooking. Rendered bacon fat and tallow serve a similar purpose, adding flavor to leaner cuts that might otherwise taste flat.
Organ meats bring their own intensity. Some companies sell freeze-dried liver powder, which you can sprinkle on ground beef or steaks for a savory, almost umami-like boost. Crispy bacon bits, egg yolks, and aged cheeses like parmesan (if you tolerate dairy) all add complexity without leaving the animal kingdom.
Cooking technique matters as much as what you add. A hard sear in a cast-iron pan creates a crust with deep, caramelized flavor that no amount of garlic powder can replicate. Letting meat come to room temperature before cooking and salting it generously 30 to 60 minutes ahead of time draws moisture to the surface, which improves browning.
Spices and Herbs: Where Most Debate Happens
Black pepper, garlic powder, onion powder, paprika, cumin, chili flakes, rosemary, thyme: these are all plant-derived, which technically puts them outside the carnivore framework. In practice, though, many carnivore dieters use them without issue.
The argument for allowing them is straightforward. You’re using a quarter teaspoon of black pepper, not eating a bowl of vegetables. The plant compounds present in that amount are negligible. The argument against is equally simple: if you’re doing an elimination diet to identify food sensitivities, even trace amounts of plant material can muddy the results. Pepper and paprika, for instance, come from the nightshade family, which some people react to.
If you’re new to the diet and trying it for health reasons, starting with salt only for the first 30 to 60 days gives you a clean baseline. After that, you can reintroduce individual spices one at a time and see how you feel. If you’re following the diet primarily for body composition or simplicity rather than as an elimination protocol, using basic spices from the start is common and unlikely to interfere with your goals.
Condiments and Liquid Seasonings
Most commercial condiments are off limits. Ketchup, barbecue sauce, teriyaki sauce, and steak sauces almost always contain sugar, corn syrup, or seed oils. Even mustard, which seems simple, often includes vinegar and turmeric, both plant-derived.
Fish sauce is an interesting exception. It’s made from fermented fish and salt, which sounds perfectly carnivore. The catch is that most brands add sugar. Red Boat is one of the few widely available brands made with only anchovies and salt, making it one of the rare bottled condiments that fits a strict carnivore approach. A few drops add a powerful savory depth to ground beef or burger patties.
Hot sauce is another gray area. The base ingredients are peppers (a plant) and vinegar, but some relaxed carnivore followers use it in small amounts. If you tolerate nightshades and aren’t doing a strict elimination, a splash of a simple hot sauce with no sugar is on the more permissive end of the spectrum.
Watch for Hidden Ingredients in Blends
If you buy pre-made seasoning blends, read the ingredients carefully. Many contain maltodextrin, cornstarch, soy lecithin, sugar, or dextrose as fillers, flow agents, or flavor carriers. “Steak seasoning” and “grill rubs” are common offenders: they often list sugar or brown sugar within the first few ingredients.
Anti-caking agents are another hidden addition. Ingredients like microcrystalline cellulose (powdered cellulose) and sodium aluminosilicate are plant-derived or synthetic compounds added to keep powders from clumping. Because they’re used in such tiny quantities, FDA guidelines allow manufacturers to omit them from ingredient labels entirely. For most people this is irrelevant, but if you’re trying to maintain a truly strict protocol, buying whole peppercorns and grinding them yourself, or using single-ingredient spice jars from reputable brands, gives you more control.
The simplest approach: buy individual spices rather than blends, and look for products with a single ingredient on the label. A jar of garlic powder should contain garlic powder and nothing else.
