Cheesy Caramelized Onion & Mushroom Dip

  • Yield: 4 1x


  • 2 sweet onions (thinly sliced)
  • 1 tablespoon canola oil (plus 1 teaspoon)
  • 1 cup freshly grated parmesan cheese
  • 1 8 ounce package cream cheese, at room temperature
  • 1/2 cup sour cream (or plain greek yogurt)
  • 1/2 cup mayonnaise
  • 1/2 teaspoon salt
  • 1/2 teaspoon pepper
  • 1 cup crimini mushrooms (chopped (use your favorite kind of mushrooms))
  • Sliced and toasted baguette for serving


  1. 1) Heat a large nonstick skillet over medium heat and add 1 tablespoon of oil. Add the sliced onions and a sprinkle of salt. I know it seems like a lot of onions, but they will wilt down. Cook over medium heat for about 10 minutes until onions begin to soften. Turn heat to low and cook for another 20-30 minutes until onions begin to caramelize.
  2. 2) While the onions cook add the parmesan, cream cheese, sour cream, mayonnaise, salt, and pepper to a large bowl and mix until thoroughly combined. Set aside.
  3. 3) Preheat oven to 400 degrees. Once the onions have been cooking for 20-30 minutes add chopped mushrooms to the pan along with 1 teaspoon of canola oil and cook for another 5-10 minutes until mushrooms are soft.
  4. 4) Add the onions and mushrooms to the cheese mixture and stir. Pour the entire mixture into an oven-safe pan and bake for 20 minutes until the top is brown and bubbly. Serve hot with toasted baguette.
