This sauce is cozy, savory, and full of flavor. You’ve got sweet, jammy caramelized onions paired with tangy Dijon and creamy cottage cheese. It tastes fancy but comes together with simple ingredients. Once blended, it’s silky and rich—like French onion dip got a gourmet upgrade.
Why I Love This Recipe
I made this sauce after caramelizing way too many onions for dinner (not that that’s ever a bad thing). I had cottage cheese in the fridge and decided to blend it all together with a little Dijon. The result? Absolute magic. It’s creamy and savory with a subtle sweetness and a tangy kick.

🔬 Why This Recipe Works (Quick Science)
- Slow-cooked onions develop natural sugars, giving the sauce a deep, sweet flavor.
- Cottage cheese creates a thick, creamy texture without needing cream or butter.
- Dijon mustard brightens the sauce with acidity and bite, balancing the richness.
- Blending while warm helps everything emulsify into a silky smooth sauce.
Ingredients
- 1 tbsp olive oil
- 1 large yellow onion, thinly sliced
- ¼ tsp salt
- ½ tsp sugar (optional, helps caramelize)
- 1 cup low-fat cottage cheese
- 1 tbsp Dijon mustard
- ¼ tsp black pepper
- 1 tbsp water or broth (to thin, if needed)
How to Make Cottage Cheese Caramelized Onion Dijon Sauce
1. Slice the Onion Thin
Slice 1 large yellow onion into thin strips.
2. Caramelize the Onions
Heat olive oil in a skillet over medium-low heat. Add onions, salt, and sugar. Cook slowly for 20–25 minutes, stirring often, until deep golden brown.
3. Blend With Cottage Cheese and Dijon
Transfer warm caramelized onions to a blender. Add cottage cheese, Dijon mustard, and black pepper. Blend until creamy.
4. Add Water to Thin, If Needed
If the sauce is too thick, blend in a splash of water or broth until pourable.
5. Reheat Gently (Optional)
Pour the sauce back into a skillet and warm over low heat for 1–2 minutes before serving.
