    🍴Ingredient Notes

    Ingredients measured out for pesto mushroom pasta.
    • Gluten-Free Pasta - I used Jovial Brown Rice Pasta, but any gluten-free pasta will work with this recipe.
    • Baby Bella Mushrooms - These are my personal favorites - you can purchase them pre-sliced to save on prep time!
    • Sweet Onion - Thinly sliced sweet onion is best. You can also swap for a red onion.
    • Basil - Fresh basil is what gives this recipe a lot of the flavor. Make sure you pack the basil into the measuring cups.
    • Raw Cashews - It's important to use raw cashews without added salt or oils. I found mine at Trader Joe's! You can also sub for pine nuts which is usually found in traditional pesto recipes.
    • Lemon Juice - Fresh or pre-squeezed lemon juice will work. (Fresh is always best!)
    • Olive Oil - I would not swap for any other oils. You'll need olive oil for the pesto and to cook the onions & mushrooms.
    • Garlic - Fresh garlic works best for this recipe, but you can also swap for ½ teaspoon of garlic powder.
    • Spices - Pesto is a simple recipe that doesn't require many spices! Just add salt and black pepper to enhance the other flavors.

    🍴Step by Step Instructions

    Step 1: Blend Pesto

    Start by adding all ingredients in a food processor or blender. Blend until pesto is a smooth and creamy consistency. (Add water if needed.)
