Ingredients You’ll Need

The magic really happens with a few simple ingredients that bring out the deepest flavors when cooked patiently. Keep an eye out for good quality sun-dried tomatoes – those packed in olive oil are my favorite because they add an extra layer of richness.

• Olive oil (or water): I often use the oil from my sun-dried tomato jar here for extra flavor but plain olive oil works beautifully.
• Yellow onions: Thin slices caramelize evenly, lending sweetness and body to the sauce.
• Garlic: Minced fresh garlic adds just that right kick without overpowering.
• Sun-dried tomatoes: Chopped finely so they meld seamlessly into the sauce.
• Salt: Helps with caramelizing and draws out moisture from onions.
• Fresh thyme: Its subtle earthiness complements sweet and tangy flavors.
• Dry white wine: Adding acidity and helps deglaze the pan for a flavorful base.
• Pasta water: Reserved starchy water helps create a silky sauce.
• Farfalle pasta: Bowtie shapes hold onto sauce in all the best nooks and crannies.
• Cashew cream (or vegan cream): Adds creaminess with a gentle nutty note.
• Spinach: A handful stirred in at the end for freshness and color.
• Salt and pepper: To taste and to brighten the whole dish.

Variations

I love keeping this recipe flexible, so you can make it your own. Feel free to experiment with different herbs or add-ins that suit your mood or pantry stash—this pasta welcomes creativity.

• Swap the Herbs: Sometimes I switch thyme for fresh basil or oregano, which brings a different aroma but just as much depth.
• Add Protein: Grilled chicken or sautéed mushrooms work beautifully if you want a heartier meal.
• Make it Spicy: A pinch or two of red pepper flakes adds a lovely warming kick.
• Use Different Pasta: Penne or rigatoni hold the sauce well, but I just adore farfalle for its fun shape.

How to Make Caramelized Onion and Sun-Dried Tomato Pasta Recipe

Step 1: Slowly Caramelize the Onions and Garlic

Heat your olive oil or sun-dried tomato oil in a non-stick pan over medium-low heat. Add the thinly sliced onions, minced garlic, and salt—don’t rush this part! Let the onions cook gently for around 25 minutes, stirring occasionally. You’ll see them transform into a golden, sweetly fragrant layer of caramelized goodness. If the pan starts to dry out, just add a splash of water to keep them from burning. This slow process is key to deep flavor, so patience here pays off big time.

Step 2: Cook Your Pasta and Reserve Pasta Water

While the onions are caramelizing, cook your farfalle according to package instructions until just al dente. When you drain it, be sure to scoop out and save about 1 1/2 cups of that starchy pasta water. It’s liquid gold for your sauce! Trust me, the leftover pasta water helps bind everything together with a lovely silky texture.

Step 3: Build the Sauce with Sun-Dried Tomatoes, Thyme, and Wine

Once your onions are beautifully caramelized, stir in the chopped sun-dried tomatoes and fresh thyme. Pour in the dry white wine to deglaze the pan, scraping up any delicious browned bits on the bottom. Let the wine reduce for a couple of minutes – this concentrates the flavors and brings a nice acidity to balance the sweetness.

Step 4: Finish the Sauce with Cashew Cream and Pasta

Now pour in the reserved pasta water and the cashew cream. Stir everything gently over low heat until the sauce turns creamy and luscious. Add the cooked pasta into the pan and toss to coat every bowtie with that dreamy sauce. Just before serving, throw in a handful of fresh spinach for a pop of green and freshness. Season with salt and pepper to taste, and your dish is ready to enjoy.

How to Serve Caramelized Onion and Sun-Dried Tomato Pasta Recipe

Garnishes

My go-to garnishes for this dish are freshly grated vegan Parmesan or nutritional yeast and a few fresh thyme leaves or basil to brighten up every bite. Sometimes, I drizzle a little extra virgin olive oil on top or add a crack of black pepper for some kick.

Side Dishes

This pasta pairs wonderfully with a crisp green salad drizzled with lemon vinaigrette, or some roasted veggies for a boost of warmth and earthiness. Garlic bread or toasted baguette slices make a perfect partner too, especially when you want to scoop up every last bit of that creamy sauce.

Creative Ways to Present

For special dinners, I like serving this pasta in deep bowls topped with microgreens or edible flowers. You can also twist it up by layering the pasta in a glass casserole dish for a beautiful presentation at family gatherings. It looks stunning when paired with a rustic wooden board and fresh herb sprigs for that cozy, inviting vibe.

Make Ahead and Storage

Storing Leftovers

Once cooled, I transfer leftovers into an airtight container and store them in the fridge. It keeps well for up to 3 days, and the flavors actually meld beautifully overnight, making it even tastier the next day.

Freezing

I don’t usually freeze this pasta because the texture of cream-based sauces can change, but if you want to, freeze it without the spinach and fresh herbs. Thaw slowly in the fridge and add fresh greens after reheating.

Reheating

The best way to reheat is gently on the stovetop over low heat, adding a splash of water or more cashew cream as needed to loosen the sauce without drying it out. Microwave works too, just heat in 30-second increments, stirring in between.
