Pesto-stuffed mushrooms make a pretty, delicious appetizer or side dish. They’re great for parties because you can make them in advance.
I make this delicious appetizer quite often when we host. And when I happen to have leftover pesto sauce, I also make it for my family, as a tasty and nutritious side dish.
These mushrooms are incredibly flavorful. The combination of the earthy mushrooms and the savory pesto sauce is incredible!
The ingredients you’ll need
You’ll only need a few simple ingredients to make this tasty appetizer. The exact measurements are included in the recipe card below. Here’s an overview of what you’ll need:
Large Cremini mushrooms: I love their color and flavor, but you can use white mushrooms too.
Olive oil: Extra-virgin is the most flavorful.
Kosher salt and black pepper: if you use fine salt, use half the amount listed.
Pine nuts: They add great flavor and some crunch! Just make sure they are fresh.
Pesto sauce: Use homemade or store-bought (but check the ingredients list).
How to make pesto-stuffed mushrooms
Scroll down to the recipe card for the detailed instructions. It’s a truly easy recipe! Here are the basic steps:
1. Wipe the mushrooms clean. You don’t want to wash them – they tend to soak up the water and become soggy.
2. Saute them briefly in olive oil. You can also cook them in butter.
3. Stuff them with pesto sauce, homemade or store-bought, then top them with toasted pine nuts.
You can serve this appetizer immediately – it’s good either warm or at room temperature. Or you can refrigerate, and then when you’re ready to serve, reheat in the oven.
What pesto sauce to use
You can certainly use store-bought pesto sauce in this recipe. But check the ingredients carefully. Many packaged pesto sauces are made with soybean oil instead of olive oil. If you want to ensure you’re using the best sauce, it’s very easy to make homemade pesto sauce.
How to serve pesto-stuffed mushrooms
I usually serve them as a party appetizer. But when I make them as a side dish for my family, I often serve them with simple meat or fish dishes such as baked chicken breast, reverse-seared steak, or baked cod.
