One-Pot Broccolini and Garlic Oil Pasta
A classic Italian aglio e olio-style pasta made entirely in one pot with fresh broccolini, thinly sliced garlic, red pepper flakes, and quality olive oil finished with bright lemon juice. The pasta cooks directly in the same pot where the garlic infuses into the oil, creating a silky sauce that coats every strand. Ready in under 30 minutes with minimal cleanup.
Steps
Before you start
- Trim broccolini by cutting off the bottom 1-inch of woody stems and halving any thick stalks lengthwise
- Have all ingredients prepped and within arm's reach of your cooktop
- Fill a large pot with 6 cups water and bring to a boil
Boil water and add pasta
- Bring 6 cups (1.4 L) water to a rolling boil in your large pot.
- Add 1 tablespoon kosher salt.
- Stir in the pasta and cook for 2 minutes less than the package directions (the pasta will finish cooking in the pot with the broccolini and oil).
- Stir occasionally to prevent sticking.

Ready when: Pasta is flexible but still slightly firm in the center
Tip: Save the water before draining—you'll need 0.5 cup of the starchy liquid to finish the sauce.
Add broccolini and drain
- When the pasta reaches the 2-minutes-short mark, add the trimmed broccolini to the pot and stir well.
- Cook together for 1 minute.
- Then drain everything in a colander, reserving 0.5 cup of the starchy pasta cooking water.
- Set the pasta and broccolini aside in the colander.

Ready when: Broccolini is tender-crisp and pasta is bendable
Tip: Don't drain the pasta completely—a little water on it won't hurt, as it will evaporate during the oil finish.
Infuse oil with garlic
- Return the empty pot to medium heat.
- Pour in the 0.5 cup (120 ml) extra-virgin olive oil and add the thinly sliced garlic.
- Cook gently, stirring often, for 2–3 minutes until the garlic softens and turns pale golden but does not brown.
- Add the red pepper flakes and cook for another 30 seconds, stirring constantly.

Ready when: Garlic is soft, translucent, and lightly golden; oil smells fragrant
Tip: Watch closely—garlic burns quickly and tastes bitter. If it starts to turn dark brown, immediately pour in the reserved pasta water to stop the cooking.
Combine pasta and broccolini with oil
- Add the drained pasta and broccolini back into the pot with the garlic oil.
- Pour in the 0.5 cup (120 ml) reserved starchy pasta water.
- Toss everything together with a wooden spoon or pasta fork for about 1 minute over medium heat, so the pasta absorbs the oil and the starch emulsifies into a silky sauce.

Ready when: Pasta is glossy and coated; the mixture looks creamy and moves as one
Tip: Toss gently but thoroughly—the starch from the pasta water and the oil create the sauce, so don't skip this step.
Finish with lemon and seasoning
- Remove from heat.
- Squeeze the lemon juice into the pot and sprinkle the finely grated lemon zest over the top.
- Add a few pinches of kosher salt and freshly ground black pepper to taste.
- Toss one final time until everything is combined.

Ready when: Bright yellow flecks of lemon zest are visible; flavors are balanced
Tip: Add the lemon juice just before serving to keep the flavor bright and prevent the acid from making the dish taste stale if it sits.
Serve immediately
- Divide among four shallow bowls.
- Drizzle a little extra extra-virgin olive oil on top if desired, and serve at once while the pasta is warm and the oil is still silky.

Tip: This dish is best enjoyed immediately—the oil begins to separate if it cools.
Good to know
Tips
- Garlic quality matters—use fresh, firm cloves. Pre-minced or jarred garlic won't deliver the same delicate flavor and silky texture when infused in oil.
- Don't skip the reserved pasta water. The starch is essential for turning the oil into a creamy sauce that clings to every strand.
- For extra richness, stir in a handful of finely grated Pecorino Romano or Parmigiano-Reggiano at the end, but taste first—the oil and lemon are already quite satisfying.
- If broccolini is unavailable or out of season, this method works beautifully with garlic spinach, tender green beans, or even thin asparagus cut into 2-inch pieces.
Storage & reheating
This dish is best eaten fresh and warm. Leftovers can be stored in an airtight container in the refrigerator for up to 2 days, but the oil will firm up and the texture will not be as silky. Reheat gently in a pan over low heat with a splash of extra olive oil and a few tablespoons of water to restore the sauce.
Substitutions
- fresh broccolini → broccoli florets or tender kale leaves. Broccoli florets will take about the same time; kale should be thinly sliced and added with the oil for 1–2 minutes to soften.
- spaghetti or linguine → pappardelle, fettuccine, or dried linguine. Any long, flat pasta works; adjust cooking time according to package directions. This recipe also works beautifully with fresh egg pasta.
- red pepper flakes → pinch of cayenne pepper or omit entirely. Adjust heat to your preference; cayenne is more potent, so start with a small amount.
- fresh lemon → 1 tablespoon fresh lime juice plus lime zest. Lime gives a different but equally bright finish; use the same amount of zest.
