Discover how to make this unique vegetarian pasta featuring caramelized onions and rutabaga in a creamy, sophisticated sauce. This unexpected rigatoni recipe transforms humble root vegetables into a restaurant-quality dish that’s both comforting and elegant.
Why You’ll Love This Rutabaga Pasta Recipe
This innovative vegetarian pasta recipe offers a delicious alternative to traditional tomato-based dishes. The combination of caramelized onions and rutabaga creates a deeply flavored, velvety sauce that coats each piece of rigatoni. This rutabaga pasta recipe provides sophisticated flavor with straightforward preparation and is balanced with fresh herbs, peppery arugula, and tangy feta cheese.
The Secret to this Caramelized Onion Pasta
Caramelized onions, slowly cooked until golden, form the base of this pasta dish, providing natural sweetness and depth. The recipe uses these onions in two ways: half are kept whole and tossed with the pasta for texture and visible pieces, while the other half are blended into the sauce. This technique ensures the onion flavor is distributed throughout the dish while maintaining some textural contrast.
How Rutabaga Transforms This Pasta Dish
Rutabaga might seem like an unusual pasta ingredient, but it brings multiple benefits to this recipe:
- Natural earthiness that grounds the dish’s flavor profile
- Subtle sweetness that complements the caramelized onions
- Creamy texture when blended that creates a velvety sauce
- Nutritional benefits including vitamins, minerals, and fiber
When cooked until tender and pureed with the onions, rutabaga creates a sauce with remarkable depth and complexity. Its earthy character balances perfectly with the aromatic elements of the dish, creating something far more interesting than standard cream sauce.
Creating the Perfect Rutabaga Cream Sauce
This one-pan sauce comes together with remarkable ease while delivering gourmet results. After caramelizing the onions, the rutabaga is added to the same pan along with:
- Aromatic garlic for depth
- Vegetable broth for savory notes
- Fresh thyme for herbal complexity
- A touch of cream for richness
- Dijon mustard for subtle tang
- Nutmeg for warmth
- Sherry vinegar for brightness
Using an immersion blender directly in the pan creates a smooth, velvety texture while maintaining all the concentrated flavors. This technique also minimizes cleanup, making this sophisticated dish surprisingly practical for weeknight cooking.
The Perfect Finishing Touches
What truly elevates this pasta dish are the final components that add both flavor and textural contrast:
- Al dente rigatoni: The pasta’s tubular shape captures the sauce perfectly
- Fresh arugula: Adds peppery brightness that cuts through the richness
- Crumbled feta: Provides tangy, salty notes that balance the sweet elements
- Toasted pumpkin seeds (pepitas): Contribute essential crunch and nutty flavor
These elements transform a good pasta dish into an exceptional one by ensuring each bite offers multiple flavor experiences and textural contrasts.
Why This Vegetarian Pasta Recipe Works
This rutabaga rigatoni succeeds by balancing multiple elements:
- The natural sweetness of caramelized onions with the earthiness of rutabaga
- Creamy texture with bright, acidic notes from vinegar and feta

The result is a vegetarian pasta dish that’s simultaneously sophisticated and comforting—hearty enough to satisfy without being heavy. It demonstrates how humble ingredients can be transformed into something exceptional through thoughtful preparation.
Pair it with a crisp white wine like Sauvignon Blanc or Pinot Grigio to complement the creamy sauce, or serve alongside a simple green salad dressed with lemon vinaigrette for a complete meal.

Ingredients
12 ounces rigatoni pasta
2 large yellow onions, thinly sliced
2 tablespoons extra virgin olive oil
1 medium rutabaga, peeled and diced
3 cloves of garlic, minced
2 cups vegetable broth
1/2 cup heavy crean
1 teaspoon Dijon mustard
1/4 teaspoon nutmeg
1 teaspoon fresh thyme
1 tablespoon sherry vinegar
2 cups arugula
1/4 cup toasted pumpkin seeds
1/2 cup feta cheese, crumbled
to taste, salt and ground black pepper
Directions
- Caramelize the Onions:
Heat the extra virgin olive oil in a large skillet over medium-low heat. Add the sliced onions and a pinch of salt. Cook slowly for 25–30 minutes, stirring occasionally, until golden brown and caramelized. Once done, remove about half of the caramelized onions and set them aside for later. - Cook the Rutabaga:
While the onions are caramelizing, place diced rutabaga in a pot of salted boiling water. Cook for 10–15 minutes until fork-tender. Drain and set aside. - Build the Sauce:
Add the minced garlic to the pan with the remaining caramelized onions. Cook for 1-2 minutes until fragrant. Add the cooked rutabaga, vegetable broth, heavy cream, Dijon mustard, nutmeg, thyme, and sherry vinegar. Simmer for 5-7 minutes to let the flavors develop. - Blend the Sauce:
Use an immersion blender directly in the pan to puree the mixture until smooth and creamy. Or, carefully transfer the mixture to a blender and blend until smooth. Season to taste with salt and ground black pepper to taste. - Cook the Pasta:
Boil the rigatoni in well-salted water until al dente. Reserve 1/2 cup pasta water, then drain. - Bring It All Together:
Return the cooked pasta to the pan with the sauce. Stir in the reserved caramelized onions and arugula. Toss to combine, adding a splash of pasta water if needed to loosen the sauce. - Serve:
Plate the pasta and top with crumbled feta, toasted pumpkin seeds, a few extra thyme leaves, and a crack of black pepper. Optional: a light drizzle of olive oil or another splash of sherry vinegar just before serving.
