It cooks fast, and the sauce comes together with zero fancy steps. Blend it, stir it in, and you’re done.
It’s the kind of meal that feels nostalgic, cozy, and just plain good—whether you eat plant-based all the time or not.

What You’ll Need for This Vegan Mac
It’s a short list with a big payoff. We make the sauce separately while the pasta cooks, then stir it all together at the end.
- Elbow Pasta – Classic shape, holds sauce well
- Raw Cashews – Soaked and blended for creaminess
- Nutritional Yeast – Adds cheesy flavor without dairy
- Garlic & Onion Powder – For depth and warmth
- Dijon Mustard & Lemon Juice – Adds tang and brightness
- Vegetable Broth – Cooks the pasta and blends into the sauce
- Salt & Turmeric – For color and seasoning
Optional: add steamed veggies or top with breadcrumbs for a little crunch.
How to Make It in the Instant Pot
This version skips the stovetop mess and gets everything done in one pot.
- Cook the pasta – Add pasta and broth to the Instant Pot. Lock the lid and cook on high pressure for 5 minutes, then quick release.
- Make the sauce – While pasta cooks, blend soaked cashews, nutritional yeast, garlic powder, onion powder, mustard, lemon juice, salt, turmeric, and a splash of water or broth until smooth.
- Drain if needed – If there’s excess broth in the pot, you can drain a little (leave some for creaminess).
- Stir it all together – Pour the sauce into the pasta, stir well, and heat on sauté if you want it extra warm and creamy.
- Serve hot – Sprinkle with paprika, black pepper, or nutritional yeast on top.
That’s it. It’s all done in under 20 minutes—and tastes like it took longer.

How to Store and Reheat It
This mac holds up surprisingly well, even without the dairy. Just know it thickens as it sits.
Storing Tips
Cool completely and store in an airtight container in the fridge for up to 4 days.
You can freeze it, but the texture might change slightly when thawed.
Reheating Tips
- Microwave: Add a splash of non-dairy milk and heat in 30-second bursts, stirring in between
- Stovetop: Warm on low with added broth or milk to loosen the sauce
- Instant Pot (Sauté mode): Reheat in batches gently with stirring
If it thickens too much, just stir in a bit of liquid and it’ll smooth right out.
Instant Pot Vegan Mac and Cheese FAQ
Can I skip the cashews?
Cashews make the sauce creamy. You can use sunflower seeds or a pre-made dairy-free cream as a backup.
What’s the best pasta to use?
Elbows are classic, but shells, rotini, or penne all work. Just avoid very thin pastas—they can overcook quickly.
Is it nut-free?
Use sunflower seeds instead of cashews and make sure your plant milk and broth are nut-free.
How do I make it spicier?
Add a pinch of cayenne, hot sauce, or a spoonful of chipotle in adobo to the sauce.
Can I double the recipe?
Yes, but don’t fill past the Instant Pot max line. Cooking time stays the same—just make sure you stir thoroughly after adding the sauce.
