Creamy Mushroom Dip

This Creamy Mushroom Dip is baked with baby bella and shiitake mushrooms, cream cheese, and a blend of Parmigiano Reggiano and Pecorino Romano for a warm, bubbly appetizer that disappears fast.

I started making this creamy mushroom dip shortly after my husband and I got married. It was always the first thing to go at our gathering; and honestly, it still is!

What makes this version different from most mushroom dips? Two things: I use a mix of baby bella and shiitake mushrooms (the shiitakes add a meatier, more complex flavor), and instead of the usual cheddar or Gruyère, I go with freshly grated Parmigiano Reggiano and Pecorino Romano. That Italian cheese combination gives the dip a savory depth that people can't quite place, but they definitely want more of.

It's a perfect warm appetizer for parties, game day, or really any time you want something comforting on the table. Serve it with crostini, crackers, fresh veggies, or tortilla chips - basically anything scoop able.

Key Ingredients for Creamy Mushroom Dip

Here's what goes into this dip: For full list of ingredients and measurements, see recipe card.

Baby bella mushrooms (cremini): the earthy, reliable base. I use a full 16 oz.

Shiitake mushrooms: 5 oz adds a deeper, almost umami richness. While baby bellas give you that familiar earthy flavor, shiitakes bring a meatier, almost smoky quality. If you can't find shiitakes, oyster mushrooms work, or use all cremini.

Cream cheese: the creamy backbone. You can use reduced-fat if you want to lighten things up.

Mayonnaise: adds tang and helps with the texture. Light mayo works here too.

Parmigiano Reggiano and Pecorino Romano: freshly grated is non-negotiable for the best flavor.

Vegetarian note: Traditional Parmigiano Reggiano and Pecorino Romano contain animal rennet, so they're technically not vegetarian. BelGioioso and 365 by Whole Foods both make vegetarian-friendly Parmesan alternatives that work well here.

How to Make This Mushroom Dip

See recipe card for full set of instructions.

Step 1: Sauté the mushrooms.

First, preheat your oven to 375° F. Then heat olive oil in a large skillet over medium-high heat. Add the chopped baby bella and shiitake mushrooms, onion, and garlic. Sauté for 5 to 7 minutes until the mushrooms are tender and have released their moisture. You want them golden and concentrated; not watery.

Step 2: Make the cream cheese base.

In a large mixing bowl, combine the cream cheese, mayonnaise, ¼ cup each of Parmigiano Reggiano and Pecorino Romano, parsley, black pepper, and cayenne. Stir until smooth and well blended.

Step 3: Combine and fill your baking dish.

Fold the sautéed mushroom mixture into the cream cheese base. Spoon everything into a 2-quart baking dish that's been lightly coated with cooking spray. Spread it into an even layer.

Step 4: Top and bake.

Sprinkle the remaining 2 tablespoons each of Parmigiano Reggiano and Pecorino Romano over the top. Bake at 375°F for 30 to 40 minutes until the top is golden and bubbly.

Tips for the Best Mushroom Dip

Don't overcrowd your mushrooms: Sauté them until golden and dry, not watery, so the dip stays creamy instead of soggy.

Use freshly grated cheese. Pre-shredded cheese has anti-caking agents that affect the melt and flavor.

Room temperature cream cheese mixes much easier. If you forget, microwave it for 20 seconds to soften.

What to Serve with Mushroom Dip

Toasted crostini or baguette slices are my go-to (if you love my baked balsamic bruschetta, you'll love crostini with this dip). But it works with just about anything: crackers, tortilla chips, fresh veggies like bell pepper strips or endive, or pretzel bites for game day.

If you love mushrooms as much as I do, also try my one-pot mushroom ricotta pasta. It's creamy, earthy, and comes together in one pot.

Make-Ahead and Storage

To make ahead: Assemble the dip in the baking dish (don't bake), cover tightly, and refrigerate for up to 2 days. Let it sit at room temperature for 20-30 minutes before baking.

Leftovers: Refrigerate covered for 3-4 days. Reheat at 350°F for 15–20 minutes until bubbly, or microwave in 30-second intervals. I don't recommend freezing.

Variations to Try

Add spinach. Fold in a handful of thawed, squeezed-dry frozen spinach for a mushroom-spinach dip. You might also love my vegan spinach artichoke dip.

Swap the cheeses. Try Gruyère or fontina for a different flavor profile.

Top with breadcrumbs. Mix panko with melted butter and sprinkle on top before baking for a crispy crust.
