I absolutely love making my own mayo—it tastes so much better and is significantly healthier than anything you can buy at the store. But let’s be honest, the traditional method is incredibly finicky, and after countless failed attempts, I had completely given up on homemade mayo.

That was until I discovered the immersion blender method—and it truly changed everything!

This technique is so beautifully simple that literally anyone can master it on their first try. I’m talking foolproof, fail-safe, ridiculously easy. Don’t believe me? Try it for yourself and prepare to be amazed!

What Makes This Homemade Mayo Recipe Work

This homemade mayonnaise recipe succeeds where others fail because of three key factors:

The immersion blender technique: Using a stick blender in a narrow jar creates the perfect emulsion environment, eliminating the guesswork and slow oil drizzling that causes traditional mayo methods to break.

Optimal ingredient ratios: The precise balance of one whole egg to one cup of light olive oil creates the ideal base for emulsification without overwhelming the delicate flavor profile.

Room temperature flexibility: Unlike traditional methods requiring precise temperatures, this technique works with cold eggs straight from the refrigerator, making it accessible for busy home cooks.

The science behind this method lies in creating stable fat-in-water emulsion through rapid mechanical action, which the immersion blender provides consistently every time.

Recipe Overview

This revolutionary mayonnaise method transforms intimidating traditional techniques into a foolproof 5-minute process. By combining all ingredients in a narrow jar and using an immersion blender, you’ll create restaurant-quality mayo that’s:

  • Paleo-friendly: No processed oils or additives
  • Whole30 compliant: Clean ingredients only
  • Keto-approved: High healthy fats, virtually zero carbs
  • Customizable: Endless flavor variations possible
  • Economical: Costs fraction of premium store-bought versions

The technique works by creating a rapid mechanical emulsification in a controlled environment, ensuring consistent results regardless of your cooking experience level.

Key Ingredients You’ll Need

Essential Components

Large fresh egg (room temperature or cold): Provides lecithin, the natural emulsifier that binds oil and water. Large or extra-large eggs work best for proper ratios.

Light-tasting olive oil (1 cup): The neutral flavor won’t overpower the mayo. Avoid extra virgin olive oil as it’s too strong and can create bitter notes.

Fresh lemon or lime juice (1 tablespoon): Adds essential acidity for flavor balance and helps stabilize the emulsion. Apple cider vinegar works great as an alternative.

Sea or Himalayan Salt (generous pinch): Enhances all flavors and contributes to emulsion stability.

Oil Alternatives

  • Avocado oil: Neutral flavor, heart-healthy fats
  • Almond or walnut oil: Nutty flavor, perfect for special occasions
  • Choose any neutral tasting oil, for cost-effectiveness

Optional But Recommended Add-Ins

These ingredients not only enhance flavor but actually help the mayonnaise emulsify more successfully:

Dijon mustard (1 tablespoon): Acts as an additional emulsifier thanks to its mucilage content, helping create a more stable mayo that’s less likely to break. Also adds a subtle tangy depth.

Fresh garlic clove (1 medium): Contains natural compounds that aid in emulsification while providing classic aioli flavor. The sulfur compounds in garlic help bind the oil and water phases together.

Add these ingredients along with the egg, lemon juice, and salt before pouring in the oil.

Equipment Needed

Mayonnaise ingredients laid out: fresh brown egg, bottle of light olive oil, cut lime half, and sea salt in small bowl

Let’s Make Homemade Mayonnaise

Step 1: Prepare the base Crack one whole egg directly into your glass jar. Just one egg. And yes that’s one WHOLE egg. No need to fuss about it, let it come to room temperature, give it a warm bath or anything. I swear. Just crack THE WHOLE THING right into the jar.

Add the lemon juice (or vinegar) and salt. If you opted to add mustard, garlic and / or other flavorings, now would be the right time to do that.

Step 2: Add oil: Pour the full cup of light olive oil directly over the egg mixture. No need for slow drizzling—just pour it all in at once.

Step 3: Let it settle: Allow the mixture to sit for 30 seconds. The egg will sink beneath the oil layer, creating the perfect setup for emulsification.

Step 4: Blend without moving: Insert immersion blender to the bottom of the jar. Blend on high for exactly 20 seconds without moving the blender.

Expert Tips for Success

Pro Techniques

Follow ratios exactly: While this technique is incredibly easy, mayonnaise making is still an exact science. The 1:1 ratio of egg to cup of oil is crucial for proper emulsification. Don’t eyeball measurements or adjust quantities—precision is key to success.

Temperature flexibility: Unlike traditional methods, this works with cold eggs, making it convenient for spontaneous cooking.

Jar selection matters: Use the narrowest jar that accommodates your immersion blender. Too wide and the technique won’t work properly.

Oil quality: Invest in good light-tasting olive oil. The flavor difference is significant and worth the extra cost.

Timing precision: Don’t rush the initial 20-second blend time. This creates the emulsion foundation.

Common Mistakes to Avoid

  • Using extra virgin olive oil (too strong)
  • Moving blender too early (breaks emulsion)
  • Using medium or small eggs (wrong ratios)
  • Skipping the settling time (prevents proper layering)

Storage Guidelines

  • Refrigerate immediately after making
  • Use within 7-10 days for best quality
  • Store in original jar for convenience
  • Always use clean utensils to prevent contamination

Recipe Variations and Adaptations

Flavor Variations

  • Garlic Aioli: Add 2-3 minced garlic cloves before blending
  • Herb Mayo: Fold in 2 tablespoons fresh herbs (basil, tarragon, chives)
  • Spicy Mayo: Add 1 teaspoon sriracha or ½ teaspoon cayenne
  • Dijon Mayo: Include 1 teaspoon Dijon mustard for tangy depth
  • Chipotle Mayo: Blend in 1 minced chipotle pepper in adobo sauce

Dietary Adaptations

  • Make it Vegan: Substitute aquafaba (chickpea liquid) for those avoiding eggs
  • Avocado oil mayo: Replace olive oil completely for neutral flavor
  • MCT oil blend: Mix ¼ cup MCT oil with ¾ cup light tasting olive oil for keto benefits

Troubleshooting

Problem: Mayo Won’t Thicken

Causes: Ingredient ratios not followed precisely, wrong jar size, or immersion blender moved too early Solution: Start over with fresh egg, measure ingredients exactly, ensure proper jar size, and follow timing exactly. Add herbs and spices to failed mayo and transform it into a delicious salad dressing.

Problem: Bitter Taste

Causes: Using extra virgin olive oil
Solution: Next time use light tasting olive oil, or other neutral tasting oil

Frequently Asked Questions

Q: Can I make this without an immersion blender?
A: No, the immersion blender is essential for this technique. Food processors and regular blenders won’t achieve the same results with this method.

Q: How long does homemade mayo last?
A: 7-10 days in the refrigerator when stored properly in a clean, airtight container.

Q: Is it safe to eat raw eggs?
A: Use fresh, high-quality eggs from reputable sources. Those with compromised immune systems should consult healthcare providers. Or try this egg-free version.

Q: Can I use different oils?
A: Yes, but avoid strongly flavored oils, such as Extra-Virgin Olive Oil or Coconut Oil. Extra-Light Olive Oil, Avocado Oil, and Macadamia Oil work best, but feel free to use your favorite neutral flavored oil.

Q: What if I don’t have lemon juice?
A: White wine vinegar, apple cider vinegar, or lime juice work as substitutes.

Q: Why did my mayo turn out too thin?
A: Usually caused by moving the blender too early or using the wrong jar size. Follow timing precisely.

Q: Can I make a smaller/bigger batch?
A: This recipe works best as written, although doubling the batch works if ratios are maintained and a proper jar, such as a 24oz wide mouth mason jar is used. Smaller batches are not recommended because there wouldn’t be enough volume to properly cover the immersion blender head, preventing the technique from working.


Bottom Line

This 5-minute homemade mayonnaise revolutionizes how you think about making this finicky condiment from scratch. The immersion blender technique eliminates traditional difficulties while creating superior flavor and nutrition compared to store-bought alternatives.

Perfect for Paleo, Whole30, and keto lifestyles, this mayo proves that healthy eating doesn’t require sacrificing taste or convenience. With endless customization possibilities and foolproof results, you’ll never need to buy mayo again.
