Creamy Sun Dried Tomato Pasta

The first time I made this sauce, my roommate stood in the doorway watching me dump cashews into the blender with this look of pure skepticism. Fifteen minutes later, she was licking the wooden spoon and asking if I could make it every week. That’s the thing about this pasta — it converts people without them ever realizing they’re eating something entirely plant-based.

I served this at a dinner party once, forgetting to mention it was vegan until everyone was halfway through their second helping. The silence was followed by someone asking why regular alfredo sauce even exists anymore. Watching skeptical friends go back for thirds is still one of my favorite kitchen moments.

Ingredients

• 350 g dried pasta: Penne catches the sauce in those little tubes, but fusilli works beautifully too. The pasta water you reserve is going to be your secret weapon for silky sauce consistency.
• 100 g sun-dried tomatoes in oil: That oil they’re packed in is liquid gold — don’t drain it down the sink. Use it to cook your onions and you’ve just amped up the flavor quotient for free.
• 1 cup raw cashews: Soaking them isn’t optional here. I learned this the hard way when I tried to skip it and ended up with grainy sauce instead of velvet.
• 2 cups unsweetened plant-based milk: Oat milk gives you the creamiest result, but almond works if that’s what you have. Just make sure it’s unsweetened — nobody wants dessert pasta.
• 3 tbsp nutritional yeast: This is what gives you that cheesy, savory depth. If you’re new to vegan cooking, this stuff is about to become your best friend.
• 2 cloves garlic: Fresh garlic makes all the difference here. Throw it in whole — peeling chopped garlic is the worst part of cooking and nobody needs that hassle.
• 1 tbsp lemon juice: Brightens everything up. The acid cuts through the rich cashew cream and makes each taste interesting.
• 1 small yellow onion: Finely chopped so they melt into the sauce rather than staying in distinct pieces. You want the sweetness, not the crunch.
• 2 cups fresh baby spinach: Wilts down to practically nothing but adds this gorgeous color contrast and makes you feel slightly virtuous about eating pasta for dinner.

Instructions

Get your pasta water going:

Salt it generously — this is your only chance to season the pasta itself. Cook it until al dente, then resist the urge to dump all that water down the drain.

Soak your cashews:

Fifteen minutes in hot water transforms them from nuts into cream. Set a timer if you’re the type to forget.

Blend the sauce base:

Combine cashews, sun-dried tomatoes, plant milk, nutritional yeast, garlic, lemon juice, oregano, salt and pepper. Blend until it’s seriously smooth — like, no-grainy-bits-whatsoever smooth.

Sauté the onion:

Use that reserved sun-dried tomato oil and cook the onion until it’s translucent. You’re building layers of flavor here.

Simmer the sauce:

Pour in that gorgeous red-orange blend and let it bubble gently for a few minutes. The kitchen will start smelling incredible right about now.

Add the spinach:

Throw it in and watch it collapse. Two minutes tops — you just want it wilted, not sad and soggy.

Bring it all together:

Toss in the pasta and add that reserved pasta water if the sauce seems too thick. It should coat each piece beautifully.

Pin it

This recipe became my go-to during grad school when I needed something that felt fancy but cost about eight dollars total. Now it’s the first thing I make when friends come over and claim they don’t like vegan food. Watching them change their minds is better than any compliment.

Making It Your Own

Sometimes I throw in roasted cherry tomatoes right at the end — they burst when you bite into them and create these little pockets of sweetness. Sautéed mushrooms work beautifully too, especially if you cook them until they’re golden and almost crispy.

What To Serve With It

A crisp white wine cuts through the richness perfectly. Sauvignon Blanc is my go-to, but sparkling water with a squeeze of lemon works if you’re skipping alcohol. A simple green salad with vinaigrette balances out the creamy pasta.

Timing & Prep Wisdom

Start soaking your cashews before you even think about anything else. I keep a jar of soaked cashews in my fridge during busy weeks — they last a few days and mean this pasta comes together in literally the time it takes to boil water.

• Double the sauce and freeze half for emergency comfort food
• Gluten-free pasta works but needs an extra minute of cooking time
• The sauce thickens in the fridge, so add a splash of plant milk when reheating leftovers

There’s something deeply satisfying about serving a dish that feels indulgent but is actually pretty good for you. This pasta is proof that comfort food doesn’t have to come with a side of guilt.

Recipe Q&A Section

→ Can I make this dish gluten-free?

Absolutely. Simply substitute regular pasta with your favorite gluten-free variety like brown rice penne, chickpea fusilli, or quinoa spaghetti. The sauce remains naturally gluten-free.

→ What can I use instead of cashews?

Sunflower seeds or peeled raw almonds make excellent alternatives. Both blend into a smooth, creamy consistency. You may need to add a bit more plant-based milk to achieve the desired texture.

→ How long does the sauce keep in the refrigerator?

The prepared sauce stores well in an airtight container for 3-4 days. When reheating, add a splash of plant-based milk or pasta water to restore the creamy consistency before tossing with freshly cooked pasta.

→ Can I freeze this dish?

The sauce freezes beautifully for up to 3 months. Freeze it separately from the pasta for best results. Thaw overnight in the refrigerator and gently warm on the stove before serving.

→ What vegetables work well in this sauce?

Beyond spinach, try adding roasted cherry tomatoes, sautéed mushrooms, diced bell peppers, or zucchini. These vegetables complement the sun-dried tomato flavors beautifully while adding extra texture and nutrients.

→ Is this dish spicy?

The base dish has mild heat from black pepper and garlic. If you enjoy spice, add crushed red pepper flakes to taste when serving. The sauce itself is rich and savory without being overly spicy.
