Equipment

Must-haves

• Large pot for pasta
• Sauté pan or skillet for caramelizing onions
• Large mixing bowl (the salad’s stage)
• Colander or strainer
• Sharp knife and cutting board
• Measuring spoons and cups
• Spatula or wooden spoon

Nice-to-haves

• Baking sheet for roasting Brussels sprouts
• Salad tongs for dramatic tossing
• Toasted nuts on a separate sheet pan
• Microplane for a hint of lemon zest (if you’re feeling fancy)
• Optional silicone scraper for easy cleaning

Ingredients

• 12 oz farfalle pasta (or your preferred short shape)
• 3 large yellow onions, thinly sliced
• 2 tbsp olive oil
• 2 tsp brown sugar
• 2 tbsp balsamic vinegar
• 2 cups Brussels sprouts, trimmed and halved
• 1 cup fresh cranberries (halved if large) or dried cranberries
• 1/2 cup toasted pecans, roughly chopped
• 1/2 cup crumbled feta cheese (optional)
• 1/2 cup fresh parsley, chopped
• 1 tbsp fresh sage, chopped (or thyme)
• Salt and pepper to taste
• Zest and juice of 1 lemon

For dressing

To keep things simple, whisk this together later: 3 tbsp olive oil, 1 tbsp lemon juice, 1 tsp Dijon mustard, 1 tsp honey or maple syrup, salt and pepper to taste. The lemon keeps it bright, the mustard keeps it confident, and the honey keeps it from swinging too far into “diet soda.”

Instructions

1. Cook the pasta in salted water until al dente, then drain and rinse with cold water. Set aside to cool slightly; that’s how you avoid a soggy salad drama.
2. Caramelize the onions: in a large skillet, heat olive oil over medium. Add onions, a pinch of salt, and the brown sugar. Cook slowly, stirring often, until they’re deeply golden and sweet—think onions on a tiny spa day. Deglaze with balsamic vinegar and set aside.
3. Roast the Brussels sprouts: preheat oven to 425°F. Toss sprouts with a splash of olive oil and a pinch of salt. Roast 15–20 minutes, until they’re tender and caramelized at the edges. Let cool slightly.
4. Make the dressing: whisk together 3 tbsp olive oil, 1 tbsp lemon juice, Dijon mustard, honey, salt, and pepper. If you’re feeling bold, add a splash of the lemon zest for extra zing.
5. Assemble: in a big bowl, combine pasta, caramelized onions, roasted Brussels sprouts, cranberries, parsley, and sage. Drizzle the dressing over the top and toss to coat everything evenly.
6. Finish with pecans and feta (if using). Adjust seasoning with a little more salt, pepper, or lemon juice to taste.
7. Serve warm or at room temperature. If you like, refrigerate for 20–30 minutes to let the flavors mingle like good friends at a reunion.

Good to Know

This salad shines with a balance of sweetness from the caramelized onions and tang from the lemony dressing. It’s a great way to use Thanksgiving leftovers without turning the fridge into a science experiment.

Tips to keep in mind: roast the Brussels sprouts separately so they get crisp, and don’t overcook the pasta—al dente keeps the bite. You can swap in dried cranberries if you don’t have fresh, but fresh adds that pop of tart juiciness.

Tips

• Caramelize the onions slowly for maximum depth—low and patient wins every time.
• Toast the pecans on a separate sheet pan to avoid soggy crunch.
• Dress the salad while it’s a touch warm so the pasta absorbs more flavor.
• Make dressing and onions a day ahead for extra convenience; just rewarm gently if you’d like them warm.
• If you’re avoiding dairy, skip feta and amp up herbs instead for brightness.

Variations

• Swap Brussels sprouts for roasted butternut squash or kale for a different fall vibe.
• Use a tangier cheese like goat cheese or omit cheese entirely for a dairy-free version.
• Try toasted almonds or walnuts instead of pecans for a different crunch.
• Switch up the greens: arugula or baby spinach can add a peppery or leafy bite.

Serving Suggestions

• Garnish with extra chopped parsley and a lemon wedge for color and a fresh zing.
• Pair with roasted turkey or a simple roasted chicken to keep the Thanksgiving vibe intact without crowding the menu.
• Offer as a potluck staple—it travels well and tastes better as flavors meld.
