Ingredients
What is Romanesco? This member if the brassica family is also known as Roman cauliflower, Romanesco broccoli, or Romanesque cauliflower.
Some people describe its mild flavor as a cross between broccoli and cauliflower.
But it's most appreciated for its yellow-green color ranging from light to almost fluorescent. And, the fractal shape of the florets are a testament to nature's artistry.
Penne pasta: Short pasta shapes like penne, rigatoni, or farfalle work well in this recipe. I like to use Ancient Harvest organic gluten-free penne made with corn, brown rice, and quinoa.
Variations

- Roasted pine nuts
- Lemon zest and a squeeze of lemon juice
- Vegan parmesan cheese
- Seasoned sauteed chickpeas

Instructions
- Toss the Romanesco florets and garlic slices in olive oil, salt, and pepper.
- Roast in the oven until lightly browned and tender when pierced with a fork.
- Cook the pasta in a large pot of salted water according to the package directions until al dente.
- Toss the cooked and drained pasta with the roasted vegetables and any remaining olive oil from the baking sheet.
Amy's tip
Reserve about half a cup of the starchy cooking water before draining the pasta. A coffee mug works well for scooping it out of the pot.
Add enough of the reserved pasta water so that it emulsifies with the olive oil and helps the vegetables stick to the pasta.
Serving suggestions
While romanesco pasta is delicious on its own, you can also serve it with a vegan salad like marinated artichokes salad or white bean and cherry tomato salad.
Or try it with an easy side dish like air fried fresh green beans or Mediterranean zucchini and tomatoes.
Storing
Leftovers can be covered and stored for up to 3 days in the refrigerator, then reheated in a microwave. Freezing is not recommended.
