Roasted Garlic & Asparagus Pasta

Featured in: Oven & Pan Cooking

This vibrant pasta dish showcases the natural sweetness of roasted whole garlic cloves, which become mellow and creamy after 30 minutes in the oven. The garlic pairs beautifully with fresh asparagus roasted to tender-crisp perfection, all tossed with al dente spaghetti in quality olive oil.

A burst of lemon zest brightens the flavors while Parmesan adds a savory finish, creating a well-balanced vegetarian main that comes together in under an hour. The technique of reserving pasta water helps create a silky sauce that clings to every strand of spaghetti.

The first time I made roasted garlic, I stood by the oven watching those little cloves turn golden, wondering how something so simple could smell so intoxicating. My entire apartment filled with this mellow sweetness that made my stomach growl in anticipation. I started roasting garlic regularly, keeping a stash in the fridge to spread on toast or stir into sauces.

Last spring, my friend Sarah came over for dinner after a brutal week at work. She took one bite of this pasta and actually went quiet, which never happens, and I knew I had something special. She asked for the recipe before she even finished her plate.

Ingredients

  • 1 large head garlic: Roasting tames the sharp bite and brings out natural sweetness that creates an instant sauce base
  • 1 bunch fresh asparagus: Look for tight buds and firm stalks, snap off the woody ends where they naturally break
  • 12 oz spaghetti: The thin strands grab onto the roasted garlic perfectly
  • 1/4 cup extra-virgin olive oil: Use your best quality oil here since it carries so much flavor
  • 1/2 teaspoon sea salt: Start with less, you can always add more at the end
  • 1/4 teaspoon freshly ground black pepper: Freshly cracked makes a noticeable difference
  • 1/4 teaspoon red pepper flakes: Optional, but I love the gentle warmth it adds
  • 1/2 cup grated Parmesan cheese: Grate it yourself for the best melt
  • Zest of 1 lemon: This brightens the rich garlic and cuts through the olive oil
  • 2 tablespoons fresh parsley: Adds fresh color and a grassy finish

My daughter helped me make this last week, and she kept sneaking roasted garlic cloves straight from the head while I was trying to mash them. I pretended not to notice.

Making This Your Own

Sometimes I add toasted pine nuts for crunch or swap in spinach when asparagus is not in season. The roasted garlic stays constant though, that is non-negotiable.

Pairing Suggestions

A crisp white wine cuts through the richness beautifully. I also like a simple arugula salad with lemon vinaigrette on the side.

Make Ahead Wisdom

You can roast the garlic and asparagus up to two days ahead, just store them in the fridge. The pasta comes together in minutes when you are ready to eat.

  • Let the roasted garlic cool completely before refrigerating
  • Reheat everything gently so you do not lose the silkiness
  • Always finish with fresh lemon zest right before serving

Recipe FAQs

How do I roast garlic properly?

Slice the top off a garlic head to expose the cloves, drizzle with olive oil, wrap tightly in foil, and roast at 400°F for 30 minutes until the cloves are soft and golden. The cloves will squeeze easily from their skins when done.

Can I use other pasta shapes?

While spaghetti works beautifully to coat the garlic and oil, you can substitute linguine, fettuccine, penne, or fusilli. Adjust cooking time according to package directions for your chosen shape.

How do I know when asparagus is done roasting?

Roast asparagus at 400°F for 12-15 minutes until tender-crisp. You should be able to pierce it easily with a fork, but it should still have a slight crunch. Avoid overcooking or it will become mushy.

Can I make this dish ahead?

Roast the garlic and asparagus up to a day in advance. Store separately in the refrigerator. Reheat gently in a skillet before tossing with freshly cooked pasta for the best texture and flavor.

What can I substitute for Parmesan?

For a vegan version, use nutritional yeast, a plant-based Parmesan alternative, or simply omit the cheese. The roasted garlic and asparagus provide plenty of flavor on their own.

Why reserve pasta water?

Pasta water contains starch that helps emulsify the olive oil and creates a silky sauce that clings to the spaghetti. Add it gradually while tossing to achieve your desired consistency.

Directions

Instruction 01

Roast the Garlic: Preheat the oven to 400°F. Slice the top off the garlic head to expose the cloves, drizzle with a small amount of olive oil, wrap tightly in aluminum foil, and roast for 30 minutes until cloves are soft and golden brown.

Instruction 02

Roast the Asparagus: After the garlic has been roasting for 15 minutes, spread the asparagus pieces on a baking sheet, drizzle with olive oil, season with salt and pepper, and roast in the same oven for 12-15 minutes until just tender-crisp.

Instruction 03

Cook the Pasta: Bring a large pot of generously salted water to a rolling boil. Cook spaghetti according to package directions until al dente. Reserve 1/2 cup of the starchy pasta water before draining thoroughly.

Instruction 04

Prepare the Roasted Garlic: Once the roasted garlic is cool enough to handle, squeeze the softened cloves from their skins. Mash the cloves lightly with a fork to create a fragrant paste.

Instruction 05

Create the Garlic Base: Heat 1/4 cup olive oil in a large skillet over medium heat. Add the mashed roasted garlic and sauté for 1-2 minutes, stirring constantly, until fragrant and infused into the oil.

Instruction 06

Combine the Components: Add the roasted asparagus and cooked spaghetti to the skillet with the garlic oil. Toss everything together thoroughly, adding the reserved pasta water a little at a time as needed to create a silky, cohesive sauce that coats the pasta.

Instruction 07

Add Finishing Ingredients: Remove the skillet from heat. Stir in the Parmesan cheese, lemon zest, chopped parsley, and red pepper flakes if using. Toss until the cheese melts and the ingredients are evenly distributed. Taste and adjust seasoning with additional salt and pepper as needed.
