Ingredients
For the Creamy Mustard Dressing (Sauce Fermière)
- 1 hard-boiled egg (approx. 50 g)
- 15 g (1 tbsp) strong Dijon mustard
- 20 ml (1 tbsp + 1 tsp) fresh lemon juice
- 100 ml (just under ½ cup) neutral oil (canola or sunflower)
- 3 g (½ tsp) salt
- 2 g (¼ tsp) black pepper
For the Salad
- 150 g (1 cup) sliced baby tomatoes
- 160 g (1½ cups) diced avocado
- 2–3 hard-boiled eggs, sliced
- 5 g (1 tbsp) chopped fresh parsley
- 5 g (1 tbsp) chopped chives
How to Make It
Step 1 – Make the Creamy Mustard Dressing
- In a tall, narrow container (like the one that comes with your immersion blender), add the hard-boiled egg, mustard, and lemon juice.
- Use a hand blender to blend until smooth.
- Slowly drizzle in the oil while blending until a thick, creamy emulsion forms.
- Season with salt and pepper. Chill until ready to use.
💡 Pro Tip: The container must be just slightly wider than the hand blender head to ensure proper emulsion. If it’s too wide, the dressing may not thicken properly.
Step 2 – Assemble the Salad
- In a large mixing bowl, combine sliced tomatoes and diced avocado.
- Gently add the sliced hard-boiled eggs.

- Pour the desired amount of mustard dressing over the salad.
- Carefully fold everything together using a silicone spatula to preserve the shape of the ingredients.
- Top with chopped parsley and chives.
- Serve immediately, or chill until serving. Add croutons or toasted bread for crunch if desired.
Smart Substitutions and Customization Tips
- No mustard? Swap it with Greek yogurt and a splash of white wine vinegar for a tangy, creamy effect.
- Dairy-free? This dressing has no milk or cream—great for dairy-free diets!
- Make it vegan: Use 1 tbsp aquafaba (chickpea water) instead of the egg in the dressing, and skip the sliced eggs.
- No cherry tomatoes? Use Roma tomatoes or heirloom varieties, chopped.
- Boost the protein: Add grilled chicken breast, tuna, or crispy bacon.
- Add texture: Include toasted walnuts, pumpkin seeds, or croutons for crunch.
- More greens? Toss in spinach, baby kale, or arugula to bulk it up.
Tips and Tricks for Success
1. Perfect Hard-Boiled Eggs
Use this foolproof method:
- Start eggs in cold water.
- Bring to a boil, then cover and remove from heat.
- Let sit for 10 minutes, then transfer to an ice bath.
- Peel once cooled for easy slicing.
2. Choose the Right Avocado
Use avocados that are ripe but not mushy. They should give slightly when pressed but still hold their shape when diced.
3. Store the Dressing Properly
Keep the dressing in an airtight jar in the fridge. It stays fresh for up to 2 days and may even thicken slightly as it chills.
4. Best Tools
- Hand blender: Ideal for emulsifying the dressing.
- Narrow container: Helps you create a thick, stable emulsion.
- Rubber spatula: Prevents the avocado and eggs from getting smashed while mixing.
Frequently Asked Questions
Can I make this avocado and egg salad in advance?
You can make the dressing 1–2 days ahead and store it in the fridge. Assemble the salad just before serving to keep the avocado fresh and vibrant.
How do I keep the avocado from browning?
Toss diced avocado with a few drops of lemon juice before mixing into the salad. This slows oxidation and keeps the color brighter for longer.
Can I use olive oil instead of neutral oil?
You can, but be aware that extra virgin olive oil will add a strong flavor. A light-tasting olive oil or avocado oil is a better substitute if you want to stay closer to the original flavor.
What kind of mustard works best?
Use Dijon mustard for the classic flavor. You can try grainy mustard for texture or spicy brown mustard if you want more kick.
How long will leftovers keep?
Once assembled, the salad is best enjoyed within 24 hours. The avocado may brown slightly over time, but the flavor will remain good if stored in an airtight container.
Serving Suggestions
- Serve over a bed of greens or with whole-grain toast for a hearty brunch.
- Pack into a glass container for an easy office lunch.
- Enjoy with soup or a light sandwich for a full meal.
- Add crumbled feta or goat cheese for extra richness.
