When it comes to pasta, there is one recipe that really hits the spot and that we’re making on repeat in our family: the lemon butter pasta with burrata. This pasta recipe is way more than just pasta and makes you feel like you just ordered a fancy dish in a restaurant. Given my obsession about it, it’s no surprise I created a slightly different version – winter edition.

These lemony winter squash pasta still have the wonderful and refreshing lemon flavors (a revelation in pasta, so good!), and they’re also combined with some roasted butternut squash, baby spinach, and generously topped with a crispy pecan-breadcrumb mixture. Don’t forget the touch of cheese – here some halloumi croutons – that complete the dish and makes it extra delicious!

Lemon winter squash in short:

  • A sophisticated pasta dish loaded with lemon flavors
  • 100% Vegetarian and loaded with veggies

What goes into lemony winter squash pasta

Instead of an exhaustive list of ingredients that you can find in the recipe card below, I’m listing here the main components of this pasta recipe:

  • Pasta (obviously). I recommend either spaghetti or other similar long pasta, such as linguine or tagliatelle. Whole wheat pasta can work too.
  • Lemons. It’s what brings all the flavors to these pasta, so make sure you’ve checked it off on your grocery list. Also, all the flavors come from the zest, not the juice, so you want to make sure you use it.
  • Winter squash. We used a butternut squash in this recipe, but other winter squash that are good for roasting would do too.
  • Baby spinach. For a touch of greens. You could replace with kale if desired.
  • Pecans. They’re crunchy and add a subtle nutty flavor to the recipe. We’re obsessed.
  • Breadcrumbs + herbs (oregano, thyme). Toasted, and combined with herbs, breadcrumbs bring a slightly crispy touch that make your pasta look fancy.
  • Halloumi. No pasta without cheese, right? There is no parmesan involved in this recipe (although there’s no harm in adding some) but instead some salty halloumi croutons for a somehow chewy bite.

How to make winter squash pasta

Because the recipe involves several steps and the pasta need to be served when still hot, it’s important to time the recipe and respect the recipe instructions carefully. To ensure you don’t get lost in the process, here are the main steps to keep in mind:

  • Start with roasting the winter squash in the oven until tender and slightly crispy.
  • While the squash is in the oven, prepare the crispy herb pecan breadcrumbs. Gently stir-fry all the ingredients together with oil and butter, and add the lemon zest at the very end. It’s totally ok if the breadcrumbs come to room temperature before using.
  • Now, cook the pasta, drain, and cook in a large skillet with butter, using some cooking pasta water, lemon juice and zest.
  • Prepare the halloumi croutons by quickly stir-frying them on all sides in a small skillet with a drizzle of olive oil (this should take a couple of minutes at most).
  • Now assemble your pasta! Distribute pasta with winter squash onto serving plates. Add a few spoonfuls of pecan breadcrumbs, and top with halloumi croutons. Garnish with additional lemon zest, sea salt and freshly ground pepper.

Pro tips for success

  • Use long pasta, such as spaghetti or linguine. Short pasta could work too, but I find that long pasta blends well with the wilted baby spinach, while the crispy breadcrumb topping is best served onto long pasta.
  • Reserve some of the cooking pasta water. When draining your pasta, reserve some of your cooking water to mix with the pasta. Starchy pasta water helps thinner the sauce to the right consistency. It’s a little trick that works for all pasta recipes.
  • Follow the instructions in the order listed in the recipe. This will help you get organized while making the recipe. The steps are also listed in such a way that the recipe will be just warm and ready to serve. If however you decide to go your own way, there’s a chance you will feel overwhelmed during the process and have cold pasta in the end – which you don’t want.
  • Add the breadcrumbs in the end. This will ensure they remain nice and crispy. There’s nothing worse than soggy breadcrumbs, and this pasta dish is no exception!

How to warm up the leftovers?

If you know there will be some leftover pasta , I recommend storing separately the winter squash pasta with halloumi and the breadcrumbs. The pasta can easily be reheated in the microwave or on the stovetop with some butter or oil. You can keep the pecan breadcrumbs covered at room temperature in a small container, and add them on the leftover pasta at the last minute. You can also re-heat in a small skillet if you want to eat them warm.

Recipe variations

There are a few ways to tweak this winter squash pasta recipe. I recommend keeping the same lemon-butter pasta base, and then play with the other ingredients. Kale can be used instead of spinach, burrata or ricotta instead of halloumi, and pine nuts instead of pecans. Like cheesy pasta? Grate some additional parmesan when serving and/or add some to the breadcrumb mixture. Pasta recipes are always very forgiving, so let your imagination guide you and please let me know if you tried a variation you love, I’d love to hear about it!

Ingredients

Scale
  • 1 medium butternut squash* (about 2.2 lbs/1kg), peeled, halved, seeded, and diced
  • 3 Tablespoons extra virgin olive oil, divided
  • 2 teaspoons dried oregano
  • Salt and freshly ground pepper
  • 6 Tablespoons butter, divided
  • 1 cup (110g) breadcrumbs
  • 1 cup (125g) pecans, chopped
  • 1 Tablespoon dried thyme or herbes de Provence
  • ½ teaspoon crushed red pepper flakes (optional)
  • Zest of 2 lemons
  • 12 oz (340g) spaghetti or other long pasta
  • 1 lemon, juice
  • 34 cloves garlic, thinly sliced
  • 10.5 oz (300g) baby spinach
  • 1 block (7 oz/200g) halloumi, cubed
  • 1 teaspoon honey (optional)

Instructions

  1. Preheat the oven to 400°F (200°C). Line a large rimmed baking sheet with parchment paper.
  2. For the winter squash. In a large mixing bowl, combine cubed winter squash with 2 Tablespoons olive oil, oregano, salt, pepper, and toss to coat. Transfer to the prepared baking sheet in an even layer, and roast, tossing halfway through, until tender and browned in spots, about 25–30 minutes.
  3. For the pecan breadcrumbs. Heat 1 Tablespoon of olive oil and 1 Tablespoon of butter (15g) in a large skillet over medium heat. Add the breadcrumbs, pecans, thyme and red pepper flakes (if using). Cook, stirring occasionally until the breadcrumbs and pecans are toasted all over, about 4-5 minutes. Add the zest from one lemon and toss quickly. Remove the breadcrumb mixture from the skillet and transfer to a shallow dish.
  4. For the pasta. Bring a large pot of salted water to a boil. Cook the pasta according to package directions until al dente. Drain and reserve ½ cup (120 ml) cooking water for later.
  5. Wipe the skillet and reuse it. Melt 4 Tablespoons butter (55g) in the skillet over medium-high heat for a couple of minutes or until butter is browning, swirling the pan as needed. Add the garlic and cook for 1 more minute, until fragrant. Add lemon juice and the zest of the other lemon, and stir.
  6. Reduce the heat to low and add ½ cup of the pasta water**, the spaghetti and the remaining 2 Tablespoons (30g) butter, tossing until melted. Add the baby spinach in 2 or 3 addition, tossing as you go until wilted. Add the roasted butternut squash and toss gently until evenly distributed.
  7. For the halloumi. Drizzle a little bit of olive oil in a small skillet placed over medium heat. Add the cubed halloumi and gently stir-fry until golden on all sides. Remove from heat, and combine with honey (optional).
  8. Serve the lemony winter squash pasta with the pecan breadcrumbs on top, and add the halloumi croutons. Grind more black pepper over the dish, add extra lemon zest for more lemony flavors, and enjoy!

Notes

* You can use other types of winter squash of choice.

** You can add more pasta water to thin the sauce.
