Creamy Sun Dried Tomato Pasta

The rainy Sunday I first made this sauce, my roommate walked in and asked if I'd been simmering tomatoes all day. Little did she know it took twenty minutes and a handful of soaked cashews to create something that rich and velvety. Now it's my go-to when I need comfort food that feels indulgent but is actually pretty simple to throw together.

Last winter I served this at a dinner party where two guests were convinced I'd hidden heavy cream in the sauce. Watching their faces when I revealed the secret ingredient was pure cashews never gets old. It's become one of those recipes I make for anyone who thinks vegan food can't be decadent.

Ingredients

• Dried pasta: Choose penne or fusilli for catching sauce, or go with spaghetti if you prefer long noodles that really show off the coating. Gluten-free works beautifully here too.
• Sun-dried tomatoes in oil: These are the flavor powerhouse of the dish. That oil they're packed in is liquid gold so save every drop for cooking.
• Raw cashews: Soaking them softens the nuts enough to blend completely smooth, creating that luxurious creaminess you'd normally get from dairy.
• Plant-based milk: Unsweetened is key here since we want savory depth. Oat milk adds extra richness while almond keeps it lighter.
• Nutritional yeast: This gives subtle cheesy notes and depth that make the sauce feel complete rather than just creamy.
• Fresh baby spinach: The leaves wilt down into the sauce, adding nutrition and a gorgeous color contrast against the orange-red sauce.
• Fresh basil: Tearing it right before serving releases aromatic oils that brighten the whole dish.

Instructions

Get your pasta going:

Drop the pasta into salted boiling water and cook until it still has a little bite to it. That pasta water you save is starchy liquid gold that helps the sauce cling to every strand.

Blend up the magic:

Toss those soaked cashews, sun-dried tomatoes, plant milk, nutritional yeast, garlic, lemon juice, and seasonings into your blender. Let it run until you see zero grainy bits and the texture looks like heavy cream.

Build flavor in the pan:

While the pasta bubbles away, heat your oil in a large skillet and cook the onion until it's translucent and sweet. This foundation matters.

Simmer the sauce:

Pour in that gorgeous orange sauce you just blended and let it bubble gently for a few minutes. The flavors deepen and it thickens slightly as it heats through.

Add the greens:

Drop in the spinach and watch it collapse into the sauce. It only takes about two minutes to go from crisp to perfectly wilted.

Bring it all together:

Add your cooked pasta right into the skillet and toss until every piece is coated. If the sauce seems too thick, splash in some of that pasta water you saved.

Finish with flair:

Serve it up while it's hot and fragrant, topped with torn basil and a pinch of red pepper flakes if you like a little warmth.

Save

My sister called me at 10pm one night, halfway through making this, worried the sauce looked too thin. I told her to trust the process and give it a few minutes in the pan. She texted back fifteen minutes later saying she'd eaten two bowls standing up at the counter.

Making It Your Own

I've discovered that adding roasted cherry tomatoes right before serving creates these little bursts of sweetness that contrast beautifully with the rich sauce. Sometimes I'll sauté mushrooms with the onion for earthiness, or stir in white beans for extra protein if I want it to feel more like a complete meal.

What To Serve Alongside

A crisp white wine like Sauvignon Blanc cuts through the creaminess perfectly, but even simple sparkling water with lemon feels refreshing against such a rich pasta. A green salad with sharp vinaigrette balances the plate nicely.

Storage And Meal Prep

The sauce keeps surprisingly well in the fridge for up to five days, though it will thicken considerably. When reheating, splash in a bit more plant milk or water to bring it back to that pourable consistency. Pasta and sauce are best stored separately to prevent the noodles from absorbing all the liquid.

• Double the sauce recipe and freeze half for an instant dinner another night
• Leftovers actually taste better the next day as the flavors really meld together
• If meal prepping, undercook the pasta slightly since it will continue absorbing liquid

Save

There's something deeply satisfying about a recipe that feels luxurious but comes together so simply. This pasta has saved countless weeknight dinners and impressed enough dinner guests to earn a permanent spot in my regular rotation.

Common Questions

→ Can I make this dish gluten-free?

Absolutely. Simply substitute regular pasta with your favorite gluten-free variety. The sauce itself is naturally gluten-free.

→ Do I need to soak the cashews?

Yes, soaking cashews in hot water for 15 minutes softens them, ensuring a perfectly smooth and creamy sauce texture when blended.

→ Can I use different plant-based milk?

Any unsweetened plant-based milk works well. Almond, soy, and oat milk are excellent choices that maintain the sauce's rich consistency.

→ How long does this keep in the refrigerator?

The dish stores well for 3-4 days when kept in an airtight container. Reheat gently with a splash of water to restore creaminess.

→ Can I make the sauce ahead of time?

Yes, the sauce can be prepared up to 2 days in advance. Store it separately and reheat before tossing with freshly cooked pasta.

→ What can I use instead of cashews?

Sunflower seeds or macadamia nuts can replace cashews, though the flavor profile will shift slightly. Both create a smooth, creamy texture.
