Embrace Wholesome Eating with Stuffed Acorn Squash

We are thrilled to finally share this incredible stuffed acorn squash recipe with you! This dish is not just a meal; it’s a culinary experience that combines ease, health, and exceptional flavor. It serves as a fantastic vegetarian main course that comes together with minimal active preparation time, primarily involving the simple process of roasting the acorn squash. The beauty of this recipe lies in its versatility, offering a wonderful foundation for countless variations to suit any palate.

Using acorn squash halves as natural, edible ‘bowls’ is a clever technique that adds a fun and practical element to your cooking. These particular stuffed acorn squash are elevated with a robust and zesty Mediterranean quinoa salad. For an extra layer of flavor and creamy texture, we highly recommend finishing them with a generous drizzle of our favorite easy tahini sauce. This pairing creates a truly unforgettable dish.

The Mediterranean quinoa salad is a vibrant blend of ingredients: protein-rich canned chickpeas, sweet cherry or grape tomatoes, finely sliced scallions, perfectly cooked quinoa, salty feta, and peppery fresh arugula. Its bright and zesty profile is perfectly balanced by the inherent sweetness and tender texture of the roasted acorn squash. The dressing for this salad is a simple yet powerful combination of fresh lemon zest, tangy lemon juice, high-quality extra virgin olive oil, and our beloved all-purpose spice blend: za’atar. This harmonious mix creates a symphony of flavors that will delight your taste buds.

The Magic of Za’atar: A Culinary Essential

We simply cannot overstate our affection for za’atar! This versatile Middle Eastern spice blend, traditionally made with dried thyme, oregano, marjoram, toasted sesame seeds, and sumac, is a true kitchen hero. It imparts a unique, earthy, tangy, and slightly nutty flavor profile that can transform any dish. Za’atar adds that distinctive ‘pop’ of flavor that makes you pause, savor, and inevitably reach for more. If you haven’t already, we strongly encourage you to stock your pantry with a jar of this incredible spice.

You’ll often find za’atar in the Middle Eastern or Mediterranean sections of larger grocery stores, specialty food markets, or readily available online. Once you discover its captivating taste, you’ll find yourself incorporating it into everything from roasted vegetables and grilled meats to hummus and salad dressings. It’s a game-changer that adds depth and complexity with minimal effort, making your everyday meals extraordinary.

Selecting and Storing Perfect Winter Squash

Choosing the right winter squash is crucial for a delicious outcome. Follow these guidelines to ensure you select the best:

  • Weight Matters: Always pick a winter squash that feels surprisingly heavy for its size. This indicates a dense flesh and good maturity.
  • Deep Color & Firmness: Look for hard, deep-colored flesh with as few blemishes as possible. A tender rind suggests an immature squash, which typically results in a lackluster taste and watery texture. If you can easily puncture the skin with your fingernail, it’s best to choose another. While variations in color (excluding spaghetti squash) generally don’t impact flavor, a firm, unblemished skin is key for all other winter squash varieties.
  • Avoid Ethylene Producers: To prolong the shelf life of your winter squash, steer clear of storing it near ethylene-producing fruits like apples, avocados, and bananas. Ethylene gas accelerates the ripening process, which can cause your squash to spoil faster. Store winter squash in a cool, dry, dark place for optimal freshness.

Mastering the Art of Roasting Acorn Squash

Roasting acorn squash is a straightforward process that yields tender, sweet results perfect for stuffing. Here’s how to do it:

  • Prepare for Cutting: Acorn squash can be quite tough to cut. Use a large, sharp chef’s knife. To safely slice it in half lengthwise, it’s often easiest to set your knife slightly off-center, avoiding the very tough stem. Once cut, scoop out and discard all the seeds and any stringy, fibrous bits from the center, creating a clean cavity for your filling.
  • Ensure Stability: To prevent your squash halves from rocking on the baking sheet, a simple trick is to trim a very small slice off the rounded outer side of each squash half. This creates a flat base, ensuring they sit steadily and roast evenly.
  • Season and Roast: Arrange the acorn squash halves, cut-side up, on a sturdy baking sheet. Brush the exposed flesh generously with extra virgin olive oil, then sprinkle evenly with kosher salt and freshly ground black pepper. This seasoning enhances its natural sweetness. Roast at 450 degrees F (230°C) for approximately 45 to 50 minutes, or until the squash is beautifully caramelized around the edges and fork-tender. As it roasts, the skin will naturally begin to separate slightly from the flesh, making them perfect, practical, and edible ‘bowls’ for your delicious filling.

Expert Tips for a Flawless Mediterranean Quinoa Salad

Creating a truly outstanding Mediterranean quinoa salad involves a few key steps and considerations:

  • Pre-Cooked & Cooled Quinoa is Best: This recipe specifically calls for quinoa that has been cooked and then fully cooled. Preparing a larger batch of quinoa on the weekend is a fantastic meal prep strategy; you can then use the leftovers for various dishes throughout the week, including this one. If you don’t have cooked quinoa ready, please refer to the detailed cooking instructions provided in the recipe notes below. Cooling the quinoa helps it absorb the dressing better and prevents the salad from becoming mushy.
  • Marination for Enhanced Flavor: While your acorn squash halves are roasting to perfection, it’s the ideal time to assemble the base of your quinoa salad. Combine the chickpeas, tomatoes, scallions, lemon zest, fresh lemon juice, olive oil, za’atar, salt, and pepper in a large mixing bowl. Gently toss these ingredients together. Allowing this flavorful mixture to marinate for 20 to 30 minutes while the squash roasts will significantly improve the overall depth of flavor and seasoning, letting the ingredients meld beautifully.
  • Versatile & Make-Ahead Friendly: This vibrant Mediterranean quinoa salad is incredibly delicious even on its own! It makes for a wonderful standalone dish or a fantastic make-ahead side for various meals. If you plan to prepare it in advance, it can be stored in an airtight container in the refrigerator for 1 to 2 days. While the arugula may wilt slightly over time, it holds up surprisingly well and still contributes its fresh, peppery bite.

Equipment

  • Half Sheet Pan

Ingredients

  • 2 medium acorn squash sliced in half lengthwise, seeds removed
  • 2 tablespoons extra virgin olive oil for roasting squash
  • kosher salt to taste
  • freshly ground black pepper to taste
  • 2 tablespoons extra virgin olive oil for quinoa salad dressing
  • zest of ½ lemon, plus 2 tablespoons lemon juice
  • 1 can (15 ounces) canned chickpeas drained and rinsed
  • ½ cup (3 to 4 ounces) halved cherry or grape tomatoes
  • 3 scallions thinly sliced
  • 1 teaspoon za’atar spice
  • ¼ teaspoon kosher salt or more to taste
  • freshly ground black pepper to taste
  • cooked quinoa* cooled, see notes for cooking instructions
  • 3 ounces feta cheese crumbled
  • packed cups (1½ ounces) baby arugula leaves
  • Tahini sauce (optional) for drizzling upon serving

Instructions

  • Preheat your oven to 450°F (230°C) and position an oven rack in the center. This ensures even cooking and browning of the squash.
  • Carefully slice each acorn squash in half lengthwise using a large, sharp knife. Scoop out and discard all seeds and stringy fibers to create neat, edible ‘bowls’. To ensure the squash halves lay flat and stable on your baking sheet, trim a very small slice off the rounded outer side of each half. Brush the exposed flesh of the acorn squash generously with 2 tablespoons of extra virgin olive oil and season evenly with kosher salt and freshly ground black pepper. Arrange the squash halves, cut-side up, on the sheet pan. Roast in the preheated oven for approximately 45 to 50 minutes, or until the acorn squash is beautifully caramelized and perfectly fork-tender. Remove from oven and set aside to cool slightly.
  • While the squash is roasting, prepare the vibrant Mediterranean quinoa salad. In a large mixing bowl, whisk together the remaining 2 tablespoons of olive oil, fresh lemon zest, and lemon juice to create your dressing base. Add the drained and rinsed chickpeas, halved cherry or grape tomatoes, thinly sliced scallions, za’atar spice, ¼ teaspoon kosher salt, and freshly ground black pepper. Toss everything well to thoroughly coat the ingredients in the zesty dressing. Allow this mixture to marinate and meld flavors together while the acorn squash continues to roast. Just before you’re ready to serve, gently fold in the cooked and cooled quinoa, crumbled feta cheese, and fresh baby arugula leaves. Taste and adjust seasoning with additional salt and pepper if needed.
  • Once the roasted acorn squash has cooled slightly, fill each tender squash ‘bowl’ generously with the prepared Mediterranean quinoa salad. The salad will beautifully mound and overflow from the top. Serve immediately, and if desired, drizzle with a healthy serving of easy tahini sauce for an added layer of rich flavor. Enjoy this hearty and wholesome vegetarian meal!

Tips for Success & Variations:

  • How to Cook Perfect Quinoa: To cook 1¼ cups of quinoa for this recipe, combine 1 cup quinoa grains (ensure they are rinsed very well under cold water to remove the natural saponin layer, which can leave a soapy aftertaste), 2 cups water, and ¼ teaspoon kosher salt in a small saucepan. Bring the mixture to a rolling boil over medium-high heat. Once boiling, reduce the heat to a low simmer, cover the saucepan tightly with a lid, and cook for 17 to 20 minutes, or until all the liquid has been completely absorbed and the quinoa is fluffy. Remove from heat, let it sit covered for 5 minutes, then fluff with a fork. For quick cooling, spread the cooked quinoa in an even, thin layer on a baking sheet. This method yields approximately 3 cups of cooked quinoa, providing extra for meal prep or other dishes.
  • Make-Ahead Versatility: This Mediterranean Quinoa Salad is truly versatile and tastes just as fantastic on its own as a side dish or light lunch. It’s an excellent candidate for make-ahead meal prep. While the arugula may soften slightly when stored, the salad will hold up beautifully in a separate airtight container in the refrigerator for at least 1 to 2 days, making it perfect for busy weeknights.
  • Elevate with Tahini: While this stuffed acorn squash dish is incredibly flavorful on its own, it reaches new heights with a drizzle of this easy lemon tahini sauce. The creamy, nutty tahini complements the sweet squash and tangy quinoa salad perfectly, adding a rich depth that ties all the flavors together.
  • Customization Ideas: Feel free to experiment with this recipe! Add finely diced red onion or cucumber for extra crunch, swap out chickpeas for white beans, or introduce other fresh herbs like parsley or mint. Toasted pine nuts or slivered almonds can also add a delightful texture. For a non-vegetarian option, cooked crumbled sausage or ground turkey could be incorporated into the quinoa filling.
