Comforting, well-balanced, and quick to make, this mushroom Alfredo is likely to become a family favorite. The sauce is rich, smooth, and versatile—ideal with long or short pasta shapes alike.
Ingredients to make Mushroom Alfredo
- Cashews – The base for a creamy dairy-free sauce. If you have leftovers, they’re great in salads or stir-fries.
- Gluten-free pasta – Use spaghetti, linguine, fettuccine or short shapes like penne or fusilli.
- Olive oil – For browning the mushrooms.
- Mushrooms – Any variety works; use a single type or a mix for deeper flavor.
- Dried sage – Adds a warm, savory note.
- Paprika – Provides mild sweetness and color (smoked paprika works well too).
- Unsweetened almond milk – Or another unsweetened non-dairy milk to create the sauce’s silkiness.
- Dijon mustard – Optional; adds sharpness and depth.
- Lemon juice – A squeeze brightens the finished dish.
- Salt and pepper – To taste.
- Chopped fresh herbs – Parsley, basil, chives or coriander for garnish (optional).
See the recipe card below for exact quantities and full details.
Substitutions
- Dried sage – Swap for dried thyme if preferred.
- Paprika – Try smoked paprika for a deeper, smokier flavor.
- Dijon mustard – English mustard can be used if gluten-free; omit if you prefer no mustard flavor.
- Unsweetened almond milk – Use regular milk if you don’t need a dairy-free version.
Variations
- Spicy – Add chili paste or red pepper flakes to taste for heat.
- Deluxe – Sauté garlic with the mushrooms, increase the Dijon, stir in nutritional yeast for a cheesy note, and finish with a squeeze of lemon and a handful of spinach.
- Kid friendly – Chop mushrooms finely so they’re less noticeable, or mix with other vegetables kids enjoy.
How to make Mushroom Alfredo
Step 1: Boil the pasta according to package instructions. While the pasta cooks, heat olive oil in a large frying pan and add the roughly chopped mushrooms. Fry for about 5 minutes until softened and browned.
Step 2: Meanwhile, place the cashews and remaining sauce ingredients (dried sage, paprika, non-dairy milk, Dijon, lemon juice, salt and pepper) into a blender and blend until completely smooth.
Step 3: Pour the blended sauce into the pan with the mushrooms and stir to combine. Heat gently for 1–2 minutes—don’t cook longer, as the sauce thickens quickly.
Step 4: Drain the pasta and add it to the pan. Toss with the sauce and mushrooms until evenly coated. Finish with chopped fresh herbs if desired and season to taste with salt and pepper.
Hint: Keep heating time short—overcooking thickens the sauce too much. If needed, loosen with a splash more non-dairy milk.
Leftovers
Gluten-free pasta can lose texture if reheated repeatedly, so prepare only what you plan to eat. Store the sauce in an airtight container in the fridge for 3–4 days. You can also freeze the sauce for up to two months—leave space for expansion.
Recipe FAQs
A high-speed blender works best, but a standard cup blender will do if you soak the cashews first to soften them. Soaking helps achieve a smoother sauce with less strain on the blender.
Fried mushrooms add depth. Seasoning with paprika, sage, Dijon mustard and lemon juice enhances the sauce. Nutritional yeast can add a cheesy flavor if desired.
Traditional Alfredo contains dairy, but this cashew-based version is vegan and delivers a rich, creamy texture without animal products.
Any mushrooms work well—try a mix of chestnut, button, oyster, shiitake or portobello for varied texture and flavor.
