If you’ve been craving a creamy, silky mayo that fits a strict carnivore lifestyle, this 3-ingredient version will be your new go-to. It blends up in minutes, tastes rich and clean, and works with everything from burgers to eggs to steak. No fillers, no seed oils—just real-deal flavor.

I’ll show you exactly how to make it smooth and stable every time, even if you’ve struggled with mayo in the past. With the right fat, the right egg, and one smart acid for balance, you’ll whip up a dependable batch that never feels fussy.

Why This Easy 3-Ingredient Carnivore Mayo Works

This recipe keeps things simple and reliable, while hitting all the flavor and texture notes you want from mayonnaise.

Only three ingredients: egg, animal fat, and acid. That’s it. No sugar, no gums, no seed oils.
Thick, spreadable texture: When you emulsify slowly, the mayo turns plush and glossy.
Balanced taste: A touch of acid brightens the richness, so it never tastes heavy or flat.
Blends fast: Use an immersion blender for a foolproof, under-one-minute emulsification.
Fully carnivore-friendly: Every ingredient comes from animal sources.

Ingredients

You only need three items, plus an optional pinch of salt if you use unsalted fat.

1 large egg (room temperature works best)
1 cup rendered animal fat (beef tallow, bacon fat, or pork lard, melted and cooled to lukewarm)
1 teaspoon acid (white vinegar is classic; distilled vinegar from animal sources is ideal; you can also use strained lemon juice if you include citrus)
Optional: 1/4 to 1/2 teaspoon fine salt if your fat is unsalted

Pro tip: Use neutral-tasting fat if you want classic mayo flavor. Beef tallow tastes clean and mild. Bacon fat adds a smoky note. Leaf lard lands somewhere in between—silky and subtle.

How to Make This 3-Ingredient Carnivore Mayo

Grab a tall, narrow jar that fits your immersion blender head snugly. This shape helps the emulsion form fast.

Prep the fat: Gently melt your fat until fluid, then let it cool to just warm or room temp. Hot fat can break the emulsion.
Add base ingredients to the jar: Crack the egg into the jar. Add vinegar and salt (if using).
Pour in the fat: Add all the melted-and-cooled fat on top of the egg mixture.
Blend from the bottom: Place the immersion blender at the bottom of the jar. Turn it on and hold it steady for 10–15 seconds. You’ll see a thick, pale emulsion form at the base.
Lift slowly: Once the bottom thickens, slowly raise the blender head, letting it pull the remaining fat down and emulsify. This takes another 10–20 seconds.
Adjust thickness: If it looks too thick, blend in 1–2 teaspoons warm water. If too thin, drizzle in 1–2 tablespoons more melted-but-cool fat while blending.
Taste and tweak: Add a tiny splash more acid or a pinch of salt if needed. Blend just to combine.

Troubleshooting tip: If the mayo doesn’t thicken, your fat might be too hot, or the jar too wide. Chill the mixture for 10 minutes, then blend again, or start a new batch with one egg and slowly stream in the broken mixture as the “fat.”

How to Store Your Carnivore Mayo

Refrigerate immediately in a clean, airtight jar.
Use within 5–7 days for best texture and flavor.
Keep it cold: Store on a refrigerator shelf, not the door, to maintain a steady temperature.
Stir before using if any separation occurs. A quick whisk brings it back.

Food safety note: This recipe uses raw egg. Use the freshest eggs you can find. If you prefer, use a pasteurized shell egg to reduce risk.

Benefits of Making Carnivore Mayo at Home

Clean ingredients: No seed oils, fillers, stabilizers, or sugar.
Rich, satisfying fats: Animal fats taste full and keep you satisfied longer.
Customizable flavor: Choose your fat to control flavor—from neutral to smoky.
Budget-friendly: Rendered fat from cooking becomes a premium spread.
Quick and reliable: One jar, one blender, one minute.

What Not to Do

Don’t use hot fat: Heat breaks the emulsion and turns the mayo greasy.
Don’t skip the acid: It stabilizes the emulsion and balances richness.
Don’t use a wide container: A narrow jar helps the emulsion form instantly.
Don’t rush the blend: Keep the blender at the bottom first, then lift slowly.
Don’t store at room temp: Always refrigerate promptly.

Variations You Can Try

Keep it carnivore or bend it slightly to suit your taste and goals.

Ultra-neutral mayo: Use high-quality beef tallow for a clean, classic profile.
Smoky bacon mayo: Use filtered bacon drippings for a bold, savory spread. Fantastic on bunless burgers and steak bites.
Silky lard mayo: Leaf lard gives a delicate texture and mild flavor.
Extra tangy: Add up to 1 1/2 teaspoons vinegar for more brightness.
Garlic-forward (non-strict): If you include seasonings, whisk in a tiny pinch of garlic powder.
Mustard kick (non-strict): A 1/2 teaspoon Dijon adds bite and additional emulsifiers—handy if you struggle with thickness.
Bone broth gel boost: Blend in 1 teaspoon cooled, liquefied gelatin for added structure; chill to set slightly.

FAQ

Can I use only egg yolks?

Yes. Use 1–2 yolks instead of a whole egg for an even richer, thicker mayo. Add a teaspoon of warm water if it gets too stiff.

Which animal fat tastes best?

For a neutral flavor, choose beef tallow. For a smoky, savory profile, bacon fat wins. For a silky finish, leaf lard is great.

Why did my mayo turn grainy or loose?

Your fat was likely too hot, or you blended in a wide container. Cool the mixture and reblend, or start with a fresh egg and stream in the broken batch.

Can I make it without an immersion blender?

Yes, but it takes effort. Use a food processor or whisk by hand while drizzling in fat drop by drop. The narrow-jar immersion method stays the most reliable.

Is raw egg safe?

Use the freshest eggs and handle them properly. If you want extra assurance, use pasteurized shell eggs.

How can I make it more stable?

Use room-temperature ingredients, a narrow jar, and add the fat that’s cooled to lukewarm. A tiny splash of water helps the emulsion set.
