Ingredients You’ll Need

Each ingredient in this Caramelized Onion and Sun-Dried Tomato Pasta Recipe plays an essential role. I love using good-quality sun-dried tomatoes packed in oil to boost flavor, and fresh thyme adds a lovely herbal note that ties everything together.

• Olive oil (or water): Using the oil from the sun-dried tomato jar adds extra depth and richness to the dish.
• Yellow onions: Thinly slicing helps them cook evenly and caramelize beautifully.
• Garlic: Minced fresh garlic offers a fragrant punch that complements the sweetness of the onions.
• Sun-dried tomatoes: Chopped finely so their flavor infuses the sauce.
• Salt: Essential for drawing out moisture and enhancing natural flavors.
• Fresh thyme: This herb brightens and balances the richness of the sauce.
• Dry white wine: Helps deglaze the pan while adding subtle acidity and complexity.
• Pasta water: The starchy water is a secret weapon for creating that silky sauce texture.
• Farfalle pasta: Its bowtie shape holds the sauce perfectly, but you can swap in your favorite pasta shape.
• Cashew cream (or vegan cream): Adds luscious creaminess without dairy.
• Spinach: Just a handful to brighten up the dish and add a fresh, vibrant touch.
• Salt and pepper: To taste—season carefully for the best flavor.

Variations

I love how easy it is to tweak this Caramelized Onion and Sun-Dried Tomato Pasta Recipe to make it your own. Whether you want to boost the veggies, switch up the herbs, or try a different type of cream, there’s room to play without losing the core magic of this dish.

• Add protein: Throw in grilled chicken, sautéed mushrooms, or crispy tofu for a heartier meal—I especially enjoy it with pan-seared tofu for a vegan boost.
• Herb swaps: Swap thyme for fresh basil or rosemary, depending on what you have on hand and your flavor mood.
• Cheesy twist: If you’re not vegan, a sprinkle of Parmesan or Pecorino at the end makes it insanely comforting.
• Greens: Try kale or arugula instead of spinach for a peppery kick.

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

Step 1: Slowly Caramelize the Onions and Garlic

Start by warming your olive oil—or if you’re lucky enough to have some flavorful oil from your sun-dried tomato jar, that’s even better—in a non-stick pan over medium-low heat. Add the thinly sliced onions, minced garlic, and a sprinkle of salt. The salt helps the onions break down and draw out their natural sweetness. Here’s where patience pays off: you’ll want to stir occasionally and let the onions slowly turn golden and soft, which takes about 25 minutes. Resist the urge to crank up the heat—it’ll ruin that deep caramelized flavor you’re craving. I remember the first time I rushed this step and ended up with burnt bits; not fun!

Step 2: Cook the Pasta and Prepare Your Sauce Base

While your onions work their magic, cook the farfalle pasta according to the package instructions until al dente. Don’t forget to reserve at least 1 1/2 cups of that starchy pasta water before draining. This is a game changer for creamy sauces. Once your onions are caramelized, add in fresh thyme and chopped sun-dried tomatoes, stirring to combine. Pour in the white wine to deglaze the pan—scrape the bottom gently to lift up all those flavorful brown bits. Let it simmer for a few minutes until the wine reduces slightly.

Step 3: Bring It All Together with Cream and Spinach

Next, add your reserved pasta water and cashew cream to the pan to create a dreamy, rich sauce. Stir well and let it warm through—thicken it just slightly while the flavors meld. Then, toss in the cooked pasta right into the sauce, coating every bite. For a pop of color and freshness, stir in a handful of spinach right at the end so it wilts gently in the heat. Season with salt and pepper to taste, and you’re ready to serve.

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

Garnishes

I usually finish this pasta with a sprinkle of freshly cracked black pepper and a few leaves of basil or extra thyme sprigs for that herbal pop. Sometimes, a light drizzle of good olive oil or a little vegan Parmesan elevates it just right. I find these simple touches bring a lovely balance without overwhelming those caramelized onions and sun-dried tomatoes.

Side Dishes

This pasta stands beautifully on its own, but if you want to round out your meal, a crisp green salad with lemon vinaigrette or some garlic bread are excellent companions. My family also loves a side of roasted veggies like asparagus or zucchini to keep things colorful and fresh.

Creative Ways to Present

For a dinner party, I like serving this pasta in individual shallow bowls topped with a sprig of fresh thyme and a light dusting of vegan Parmesan. You could also plate it over a bed of lightly wilted greens and scatter toasted pine nuts on top for a textural contrast that guests always notice—and appreciate!

Make Ahead and Storage

Storing Leftovers

If you have any leftovers, store them in an airtight container in the fridge for up to 3 days. I’ve found the flavors actually deepen overnight, but the pasta can soak up the sauce a bit, so adding a splash of water or more cashew cream when reheating helps bring it back to life.

Freezing

Freezing this pasta is possible, but I recommend portioning it into freezer-safe containers and leaving out the spinach until reheating, as it doesn’t freeze well. When thawed, gently warm in a skillet with a bit of extra liquid to restore the creamy texture.

Reheating

To reheat, warm the pasta in a skillet over medium heat, adding a splash of water or cashew cream to loosen the sauce if it’s thickened too much. Stir gently until heated through, and toss in some fresh spinach or herbs for brightness before serving.
