Ingredients And Substitutions

If you have any ingredients leftover from this easy roasted broccolini recipe, check out our Leftover Ingredients Recipe Finder.

  • Broccolini: A cross between broccoli and Chinese broccoli, broccolini is slightly sweeter and more tender than regular broccoli. If unavailable, substitute with broccoli or asparagus. Use extra broccolini in Sausage and Broccolini or Vegetable Casserole.
  • Red Onion: Adds sweetness and balances the slight bitterness of broccolini. Yellow onions work as a substitute. Leftover onion can be used in Greek Chicken, Mediterranean Quinoa Salad, or Pickled Onions.
  • Kalamata Olives: Their briny, salty flavor contrasts with the sweetness of the roasted vegetables. Green olives or capers can be used instead. Use extras in Sicilian Orange Salad or Mediterranean Chicken.
  • Olive Oil: Helps the vegetables roast to a crisp.
  • Kosher Salt: I use Diamond Crystal for better seasoning control. If using table salt, reduce the amount.
  • Black Pepper: Adds a hint of heat. Adjust to taste.

Recipe Variations

Customize this recipe based on your taste or what you have on hand. Here are a few ideas:

  • Lemon Zest: Toss with lemon zest for a fresh citrus flavor.
  • Feta Cheese: Sprinkle crumbled feta over the broccolini after roasting for a tangy Mediterranean touch.
  • Garlic Roasted: Add whole peeled garlic cloves to the pan—roasting makes them soft, sweet, and buttery.
  • Toasted Pine Nuts: Sprinkle toasted pine nuts on top for added crunch.
  • Sun-Dried Tomatoes: Mix in sun-dried tomatoes for a sweet and tangy contrast.

How to Prepare Broccolini for Roasting

  1. Rinse and Dry: Wash under cold water, then dry thoroughly to help it roast evenly.
  2. Trim: The stems are edible, but if the ends feel tough, trim them slightly.

  4. Arrange: Spread in a single layer on a baking sheet, making sure not to overcrowd.
  1. Prepare the Vegetables: Arrange the broccolini on a baking sheet and scatter the sliced red onions and olives around it.

Expert Tips

  • Preheat the Oven: Make sure your oven reaches 425°F (220°C) before roasting for the best crispiness.
  • Space Evenly: Spread the broccolini out on the baking sheet to allow even cooking and browning.
  • Serve Hot: Enjoy roasted broccolini straight from the oven for the best texture and flavor.

Frequently Asked Questions

Can I use regular broccoli instead of broccolini?

Yes! Regular broccoli works well, though it may take a couple of minutes longer to roast since the stalks are thicker.

How do I store leftover roasted broccolini?

Store in an airtight container in the refrigerator for up to 2 days. Reheat in the oven at 375°F (190°C) for the best texture.

    Rating before trying but this will be a new favorite meal. I have done this with similar recipes. I just add a bit more olive oil to the mix. Then I make pasta put the roasted veggies over the pasta. The extra oil is for the pasta. Off to the store to get some broccolini!!!!
