Ingredients

For the Salad

3 medium beets, roasted and diced
2 large cucumbers, peeled and sliced
1/4 red onion, thinly sliced
1/4 cup fresh dill, chopped
2 tbsp crumbled feta cheese (optional)
2 tbsp toasted walnuts, chopped (optional)

For the Mustard Vinaigrette

3 tbsp extra virgin olive oil
2 tbsp white wine vinegar or apple cider vinegar
1 tbsp Dijon mustard
1 tsp honey or maple syrup
1 clove garlic, minced
Salt and black pepper to taste

Step-by-Step Instructions

Step 1: Roast the Beets

Preheat: Heat your oven to 400°F (200°C).

Prep: Wash the beets thoroughly, trim the tops and roots, and wrap each beet individually in aluminum foil.

Roast: Place on a baking sheet and roast for 45-60 minutes until tender when pierced with a knife.

Cool & Peel: Let cool, then peel off the skins (they should slip off easily). Dice into bite-sized cubes.

Time-saving tip: Use pre-cooked vacuum-packed beets to skip this step!

Step 2: Prepare the Vegetables

Cucumbers: Peel and slice the cucumbers into half-moons, about 1/4-inch thick.

Onion: Slice the red onion as thinly as possible. For a milder flavor, soak the slices in cold water for 10 minutes, then drain.

Fresh Herbs: Roughly chop the fresh dill.

Step 3: Make the Mustard Vinaigrette

Whisk Together: In a small bowl or jar, combine the olive oil, vinegar, Dijon mustard, honey, and minced garlic.

Season: Add salt and freshly ground black pepper to taste.

Emulsify: Whisk vigorously (or shake in a jar) until the dressing is well combined and slightly thickened.

Step 4: Assemble the Salad

Combine: In a large bowl, gently toss together the diced beets, sliced cucumbers, and red onion.

Dress: Pour the mustard vinaigrette over the vegetables and toss gently to coat evenly.

Chill: For best flavor, refrigerate for at least 30 minutes before serving to allow the flavors to meld.

Step 5: Serve

Garnish: Just before serving, sprinkle with fresh dill, crumbled feta cheese, and toasted walnuts if using.

Presentation: Serve chilled or at room temperature as a side dish or light lunch.

Recipe Variations

Add More Vegetables

Carrots: Add shredded or julienned carrots for extra crunch and sweetness.

Radishes: Thinly sliced radishes add a peppery bite and beautiful color contrast.

Arugula: Toss in a handful of arugula for a peppery green element.

Protein Boost

Chickpeas: Add a can of drained chickpeas to make this a complete meal.

Grilled Chicken: Top with sliced grilled chicken breast for a heartier salad.

Hard-Boiled Eggs: Quartered hard-boiled eggs add protein and richness.

Dressing Alternatives

Lemon-Herb: Replace vinegar with fresh lemon juice and add extra herbs.

Balsamic: Use balsamic vinegar instead of white wine vinegar for a sweeter profile.

Tahini: Mix in 1 tablespoon tahini for a creamy, nutty dressing.

Expert Tips for Success

Choosing the Right Beets

Look for firm beets with smooth skins and no soft spots. Smaller beets (about 2-3 inches in diameter) tend to be sweeter and more tender than larger ones.

Preventing Staining

Beets can stain hands and cutting boards. Wear gloves when handling, and consider using a glass or stainless steel bowl instead of plastic. Lemon juice helps remove beet stains.

Perfect Cucumber Texture

If your cucumbers have large seeds, scoop them out with a spoon before slicing. This prevents the salad from becoming watery.

Make It Ahead

This salad keeps well for 3-4 days in the refrigerator. Store the dressing separately and toss just before serving for the crispest cucumbers.

Serving Temperature

While delicious cold, letting the salad sit at room temperature for 15-20 minutes before serving brings out more flavor.

Storage Instructions

Refrigerating

Store in an airtight container in the refrigerator for up to 4 days. The beets may continue to color the other vegetables slightly, but this is normal.

Meal Prep Tips

Prep all vegetables in advance and store separately. Mix everything together and dress the salad just before serving for the best texture.

Freezing

This salad is not recommended for freezing as cucumbers become mushy when thawed. However, you can freeze roasted beets alone for up to 3 months.

Frequently Asked Questions

Can I use canned beets?

Yes! Canned or vacuum-packed beets work great and save a lot of time. Just drain and rinse them before using.

How do I keep the cucumbers from making the salad watery?

Salt the cucumber slices lightly and let them sit for 10 minutes. Pat dry before adding to the salad. This draws out excess moisture.

What can I substitute for Dijon mustard?

Regular yellow mustard works, though the flavor will be milder. Whole grain mustard adds nice texture and flavor too.

Is this salad vegan?

Yes, if you omit the optional feta cheese and use maple syrup instead of honey in the dressing.

Can I make this salad without beets?

While beets are the star, you could substitute roasted sweet potatoes or butternut squash for a different but equally delicious salad.
