Brown butter (or beurre noisette) is butter cooked gently until the milk solids turn golden brown, releasing a rich, nutty aroma. This process intensifies the flavor, making it more complex than plain melted butter.

In this salad, the brown butter lentil and sweet potato dressing adds warmth and richness that complements the natural sweetness of roasted sweet potatoes and the hearty texture of lentils. Unlike heavy creamy dressings or acidic vinaigrettes, brown butter provides a silky, savory coating that elevates the entire dish.

Step-by-Step Recipe for Brown Butter Lentil Sweet Potato Salad

1. Cooking the Lentils

Rinse lentils thoroughly under cold water to remove dust or debris.
Place them in a pot and cover with water (approx. 3 cups water per cup lentils).
Bring to a boil, reduce to simmer, and cook uncovered for about 20-25 minutes.
Test for tenderness: lentils should be soft but not mushy.
Drain and rinse with cool water to stop cooking. Set aside.

2. Roasting the Sweet Potatoes

Preheat oven to 400°F (200°C).
Peel and cube the sweet potatoes evenly (about 1-inch pieces).
Toss with olive oil, salt, and pepper.
Spread in a single layer on a parchment-lined baking sheet.
Roast for 25-30 minutes, turning once midway, until golden and caramelized.
Let cool slightly before combining.

3. Preparing the Brown Butter Dressing

Melt butter over medium heat in a small saucepan.
Swirl frequently until it foams and turns a rich golden brown with a nutty aroma (around 3-5 minutes).
Remove from heat immediately to prevent burning.
Stir in Dijon mustard, apple cider vinegar (or lemon juice), honey (or maple syrup), salt, and pepper.
Whisk until emulsified.

4. Assembling the Salad

In a large bowl, combine the cooked lentils, roasted sweet potatoes, and toasted nuts.
Add thinly sliced red onion if using.
Pour the warm brown butter dressing over the salad.
Toss gently to coat all ingredients.
Sprinkle fresh herbs on top.
Add baby spinach or arugula for extra greens if desired.
Serve warm, at room temperature, or chilled.
