Cheesy Caramelized Onion & Mushroom Dip

This will be (should be) your new go-to game day dip.

Nom nom nom nom nom.  This dip SCREAMS lazy day Sunday football.  It makes me want to curl up on the couch in my sweats, with a giant loaf of bread and dip, eat, dip, and repeat.  

It takes a little patience to make this.  Have you ever caramelized onions before?  Super easy to do, super hard to wait.  Basically you slice onions and just let them cook sloooooooooooooowly over low heat.  Low and slow baby.  The longer they cook, the more sugars are released and the more caramelized they become, thus adding more flavor to your dip!  Yaaaaaaas.

I had some leftover mushrooms so I threw them in and was super happy with the result.  Just adds an extra layer of flavor and texture.  You know I’m all about that texture.  

There’s definitely a lot creamy cheesiness happening in here.  Oh, it’s happening.  The combination of the cream cheese, salty parm, sour cream and mayo (ew, mayo), is like creamy heaven. PLEASE trust me on this.

Cheesy Caramelized Onion & Mushroom Dip

Servings 4

Ingredients

• 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

Instructions

• 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) 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) 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) 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.
