Sweet caramelized onions mixed with velvety plant-based sauce turn everyday staples into a luxurious pasta dish. The slow-cooked onions develop a golden richness that forms the backbone of this silky non-dairy sauce, boosted with tangy sun-dried tomatoes and fragrant herbs.
I've made this countless times and found that letting the onions brown slowly makes all the difference. It's become our go-to Sunday dinner - my family always comments on how amazing it is that simple onions can turn into something so incredibly tasty.
Smart Ingredient Guide
- Pasta: Both long strands and short shapes work great as they soak up the smooth sauce, with their grooves capturing every bit of flavor
- Yellow onions: These naturally sweeten as they brown, making them the perfect sauce foundation
- Fresh garlic cloves: They bring an aroma that powder or pre-minced options just can't deliver
- Balsamic glaze: Adds fancy sweetness with a slight tang that makes the whole dish pop
- Sun-dried tomatoes: The oil-packed kind add concentrated savory punch and nice texture
- Premium tamari: Brings deep flavor without gluten, making the sauce more interesting
- Italian seasoning blend: Mixes classic Mediterranean herbs that work beautifully with sweet onions
- Vegan cream: Cashew-based options give you that rich, smooth texture without any dairy
- Fresh parsley: Adds a pop of green and fresh taste to finish things off
Crafting Your Delicious Pasta
- Start With The Basics:
- Warm up your biggest pan over medium heat and pour in three tablespoons of olive oil. When it's shimmering, toss in your thinly sliced onions with a big pinch of sea salt. Cook them slowly, giving them a stir now and then with a wooden spoon, until they start getting juicy.
- Build Those Tastes:
- Watch for the edges turning golden brown as the onions cook down. Whenever the pan looks dry, splash in a little water and scrape up those tasty brown bits from the bottom. Don't rush this - it'll take about 20 minutes to get truly caramelized onions.
- Add The Aromatics:
- Throw in your chopped fresh garlic and dried herbs with those beautifully browned onions. Let them cook together until they smell amazing, releasing all their goodness into the mix. Your kitchen will smell incredible right about now.
- Cook Your Pasta:
- While your onions are doing their thing, get a big pot of water boiling. Make it salty like the ocean. Cook whatever pasta you've chosen until it's just barely firm, and save two cups of that starchy water before draining.
- Mix Everything Together:
- Add the sun-dried tomatoes, balsamic glaze, and tamari to your onion mixture. Pour in the plant-based cream and keep stirring until you've got a smooth sauce. Toss in your pasta and enough of that saved cooking water to make everything silky and well-coated.

My grandma always told me to pick the freshest yellow onions for this dish, saying they had just the right amount of sugar for caramelizing. After making this countless times over the years, I've found she was absolutely right.
Tasty Companions
Make this pasta extra special by serving it with crispy garlic broccolini, a glass of chilled white wine, and a sprinkle of toasted pine nuts. For something more casual, just add a simple peppery arugula salad with lemon dressing.
Mix It Up Ideas
Try swapping regular pasta for zucchini noodles in summer, or go for protein-packed legume pasta to boost nutrition. You can also throw in some sautéed mushrooms for more savory flavor, or mix in handfuls of fresh spinach for extra nutrients.
Storage Solutions
Keep any leftovers in a sealed container in your fridge for up to four days. When you warm it up, add a bit of water or plant milk to make it creamy again. Heat it slowly on medium-low, stirring now and then.

Frequently Asked Questions
- → Can I make this pasta gluten-free?
- You bet! Just use your go-to gluten-free pasta and switch the soy sauce for tamari. Everything else stays the same in the recipe.
- → How do I know when my onions are properly caramelized?
- Your onions are done when they've gotten much smaller and turned a rich golden brown color, looking almost like jam. This typically needs about 15-20 minutes of cooking, with regular stirring and adding liquid to prevent sticking.
- → What can I use instead of vegan cream?
- You can throw together a quick version by blending soaked cashews or sunflower seeds with water. Or try unsweetened coconut cream or a carton of oat cream from the store for this dish.
- → Can I make this pasta ahead of time?
- For sure! You can cook the onion sauce 1-2 days early and keep it in the fridge. When you're ready to eat, boil fresh pasta and warm up the sauce with a bit of pasta water to make it smooth again.
- → What proteins pair well with this pasta?
- This pasta tastes great with crispy roasted chickpeas, browned tofu pieces, white beans, or crumbled tempeh. If you aren't vegan, grilled chicken pieces or cooked shrimp would go nicely with these flavors too.
