Mustard-Free Homemade Mayonnaise (Quick Recipe)
Make mustard-free mayonnaise in about 1 minute with a pasteurized egg, neutral oil, lemon juice or vinegar, and salt. Add the ingredients to a narrow, clean vessel, then blend at the bottom before slowly lifting the immersion blender. Keep the finished mayonnaise refrigerated at or below 4°C (40°F) and use it within 3 to 4 days.
After a busy day, a simple sandwich or bowl can be just what dinner needs, but a missing condiment can add one more decision to your evening. This quick homemade mayonnaise uses pantry basics and an immersion blender, with no mustard and no cooking. The method is simple, but the order of blending matters: hold the blender still at first so the oil and egg can form a thick emulsion.
Ingredients, Vessel & Prep
This recipe makes about 1 cup of mayonnaise. It relies on a pasteurized egg, neutral oil, acid, and salt; mustard is not needed for the emulsion. Use a narrow, food-safe glass or stainless-steel vessel that fits the blender head, and start with clean hands and equipment.
| Ingredient or tool | Amount | Notes |
|---|---|---|
| Pasteurized large egg | 1, about 50 g | Use pasteurized egg for this no-cook recipe |
| Neutral oil | 240 ml (1 cup) | Canola or sunflower oil works well |
| Lemon juice or vinegar | 15 ml (1 tablespoon) | Choose one, or use a mix |
| Fine salt | ¼ teaspoon | Adjust after blending |
| Water, optional | Up to 1 teaspoon at first | Helps loosen thick mayonnaise |
| Vessel | Narrow cup or jar | Should be only slightly wider than the blender head |
Canola oil gives a mild flavor, while sunflower oil is another neutral choice. Olive oil can taste strong in a mayonnaise that is blended quickly, so choose it only if you want that flavor. Lemon juice brings a fresh, bright note; vinegar gives a sharper tang. Neither ingredient replaces the need to refrigerate the finished sauce.
For convenient blending, let the ingredients sit until they are around 18–22°C (64–72°F). This is a handling preference, not a way to make the egg safe. Keep the egg pasteurized, wash your hands and tools, and do not use raw, unpasteurized egg in this no-cook recipe.
A glass or stainless-steel vessel is a practical choice. Avoid unlined copper or aluminum, since exposed metal can react with the lemon juice or vinegar. The vessel should be clean and dry before you add the ingredients. If you plan to store the mayonnaise in another container, make sure that container is also clean and food-safe.
Fast Immersion-Blender Technique
An emulsion is a smooth mixture of ingredients that would usually separate, such as oil and water-based lemon juice. Here, the egg helps the oil disperse into tiny droplets. Keeping the blender at the bottom while the mixture thickens gives the emulsion a stable start before you draw in the rest of the oil.
- Add the egg, lemon juice or vinegar, and salt to the bottom of the vessel.
- Pour in the oil.
- Place the immersion blender head over the egg, with the head resting at the bottom.
- Blend without moving the blender for about 10–15 seconds. Look for a thick, pale mixture forming near the bottom.
- Once that thick base appears, lift the blender slowly through the oil. Continue blending for about 10–20 seconds, until the mixture looks uniform.
- Taste the mayonnaise. Add salt or acid if needed, blending briefly to combine.
The exact time can vary by blender and vessel, so use the visual cue as well as the clock. The mayonnaise should look thick and even, with no pool of oil sitting on top. If the blender head is too small for the vessel or the vessel is very wide, it may not draw the ingredients together as easily. A narrower cup helps keep the ingredients close to the blades.
Quick check: Do not lift the blender right away. The first 10–15 seconds at the bottom are the key part of this method. If the base has not thickened yet, keep the blender still for a little longer.
Safe Storage & Equipment Cleaning
Homemade mayonnaise made with egg needs prompt refrigeration. Put it in a clean, covered container and keep it at or below 4°C (40°F). Use it within 3–4 days, and discard it if it has been left out beyond the time limits below. Extra acid does not make this recipe shelf-stable.
| Situation | What to do |
|---|---|
| Refrigerator at or below 4°C (40°F) | Store covered and use within 3–4 days |
| Room temperature | Do not leave out for more than 2 hours |
| Temperature above 32°C (90°F) | Do not leave out for more than 1 hour |
| Leftover mayonnaise | Return it promptly to the refrigerator |
Serve only the amount you expect to use, then return the rest to the refrigerator. For a meal where mayonnaise will sit out, keep the serving time in mind and avoid leaving the full batch on the table for a long stretch. Do not try to extend storage by adding extra vinegar or lemon juice.
After blending, wash the vessel and blender parts with hot, soapy water. Follow the blender maker’s directions for parts that can be removed or immersed. Store the mayonnaise in the blending vessel only if it is food-safe, cleanable, and can be covered; otherwise, transfer it to a clean container.
Serving, Flavor Adjustment & Texture
This mayonnaise is a simple base for sandwiches, wraps, or a dip. Since it has no mustard, its flavor comes from the oil, acid, and salt. Taste it after blending, then make small changes so the sauce stays balanced rather than becoming too salty or sharp.
For a brighter taste, blend in a little more lemon juice or vinegar. If you prefer a softer, less sharp flavor, start with a small splash of water instead. Add salt in small pinches and taste between additions. Short blending is enough to combine these adjustments.
If the mayonnaise feels too thick, blend in cold water 1 teaspoon at a time. Stop as soon as it reaches the texture you want. Water loosens the sauce; adding more oil will make the batch larger and may make it thicker rather than fixing a texture that is already too firm.
| Desired result | Small adjustment | Check before adding more |
|---|---|---|
| Looser texture | Cold water, 1 teaspoon at a time | Blend, then check thickness |
| More tang | Lemon juice or vinegar, a small splash | Taste after each addition |
| More seasoning | Salt, a small pinch | Blend briefly and taste |
| Milder flavor | A little water | Add gradually to avoid thinning too far |
Troubleshooting & Quick Scenarios
A broken emulsion looks thin, oily, or separated instead of smooth and creamy. It can happen if the blender moves before a thick base forms, or if oil is added too fast when whisking by hand. You can often recover it by starting a fresh emulsion in a clean vessel and slowly blending in the broken mixture.
| What you see | Likely cause | What to do |
|---|---|---|
| Thin mixture from the start | Blender moved too soon, or ingredients did not come together | Try the recovery method below |
| Oil remains on top | Blender did not draw in the oil | Keep the head at the bottom until a thick base forms |
| Mayonnaise is too thick | The emulsion is firm for your intended use | Blend in cold water, 1 teaspoon at a time |
| Flavor is flat | The mixture needs more seasoning or acid | Add a small amount, blend briefly, and taste |
To recover a broken batch, add 1 teaspoon of water to a clean vessel. Blend while slowly pouring in the broken mayonnaise until it becomes smooth. Alternatively, place 1 fresh pasteurized egg yolk in a clean vessel and gradually blend in the broken mixture. Add it slowly so the new base can absorb it.
If the first attempt does not turn creamy, avoid pouring in extra oil at once. A slow, steady blend is more useful than adding more ingredients before you know what went wrong. If the sauce remains separated after a careful recovery, do not serve it as a smooth mayonnaise; start again with fresh, properly handled ingredients.
Frequently Asked Questions
These quick answers cover the common choices and fixes for homemade mayonnaise without mustard. The key points are to use pasteurized egg, start blending at the bottom, and refrigerate the finished sauce promptly. If you are making it for someone at higher risk from foodborne illness, follow the same pasteurized-egg and cold-storage guidance carefully.
Can I make mayonnaise without mustard?
Yes. Mustard is not required for this recipe. A pasteurized egg helps the oil and acid form a smooth emulsion, while lemon juice or vinegar and salt provide the flavor.
How long does homemade mayonnaise take to make?
Blending usually takes about 20–35 seconds: 10–15 seconds at the bottom, followed by about 10–20 seconds while you lift the blender. Allow a little extra time to gather ingredients and taste the finished sauce.
Can I use lemon juice instead of vinegar?
Yes. Use 1 tablespoon of lemon juice in place of 1 tablespoon of vinegar. The choice changes the flavor, so taste the mayonnaise before adding more acid.
Do the ingredients need to be room temperature?
No. Ingredients around 18–22°C (64–72°F) are convenient for blending, but this temperature is not a food-safety step. Use a pasteurized egg and keep the finished mayonnaise refrigerated.
Why did my mayonnaise stay runny?
The blender may have moved before a thick base formed, or it may not have drawn in the oil. Keep the blender at the bottom until the mixture thickens, then lift it slowly.
How can I fix mayonnaise that is too thick?
Blend in cold water 1 teaspoon at a time. Check the texture after each addition, since a small amount may be enough to loosen the sauce.
Can I use a whisk instead of an immersion blender?
Yes, but whisking takes more effort. Add the oil very slowly while whisking steadily; adding it too quickly can leave the mixture thin or separated.
How long can it sit out?
Do not leave it at room temperature for more than 2 hours, or more than 1 hour if the temperature is above 32°C (90°F). Return leftovers to the refrigerator promptly.
Is homemade mayonnaise safe for everyone?
This no-cook recipe should use pasteurized egg, not raw, unpasteurized egg. People who are pregnant, older, immunocompromised, or very young should avoid mayonnaise made with unpasteurized egg.
Can extra vinegar make it shelf-stable?
No. Extra acid does not make this recipe shelf-stable. Keep it at or below 4°C (40°F), use it within 3–4 days, and discard it if it exceeds the room-temperature limits.
