Ingredients
Here’s everything you’ll need to make this creamy French Onion Pasta Salad. I’ve added tips to make each ingredient shine:
- 2 white onions, thinly sliced – caramelizing them slowly brings out their natural sweetness.
- 3 tbsp extra virgin olive oil – use fresh, cold-pressed oil for richer flavor.
- 1/4 tsp salt – balances the sweetness of onions.
- 2-3 garlic cloves, minced – adds depth; fresh works best.
- 3/4 lb farfalle pasta – bowtie pasta holds the dressing nicely.
- 1/2 cup sour cream – gives the salad creaminess; I prefer full-fat.
- 1/4 cup mayonnaise – adds richness without overpowering flavors.
- 1/4 cup white wine vinegar – brightens the salad; avoid over-pouring.
- 2 tbsp fresh parsley, chopped – freshness lifts the dish.
- 1 tbsp chives, chopped – subtle oniony flavor, perfect garnish.
- 1 tbsp soy sauce – secret umami booster in the dressing.

Caramelize the Onions
Slice onions thinly and cook them on low in olive oil. Stir occasionally and sprinkle salt. During the last minute, add garlic and cook until fragrant.
Cook the Pasta
Boil a large pot of salted water and cook farfalle pasta according to package directions. Drain and allow it to cool slightly before combining with the dressing.

Combine Pasta and Dressing
Fold the pasta into the dressing gently. Save some caramelized onions for topping. Mix well so every piece is coated without mashing the pasta.

Top with remaining onions, chives, parsley, and a crack of black pepper. Enjoy chilled or at room temperature.
