Since that evening, I've made this salad no fewer than forty times. It's become my January tradition—a edible reset button that bridges the gap between holiday excess and spring's eventual abundance. The beauty lies in its simplicity: assertive greens that can stand up to heat, segments of orange or grapefruit that perfume the entire kitchen, and a shower of toasted nuts that add the kind of crunch that makes you close your eyes involuntarily. Whether you're serving it alongside roast chicken for Sunday dinner or eating it straight from the pan while standing at your kitchen counter (no judgment), this salad delivers the kind of deep satisfaction that makes you feel like you're doing something profoundly good for yourself.

Ingredients You'll Need

Ingredients for warm spinach and kale salad

This salad celebrates winter's finest offerings, bringing together ingredients that might seem humble on their own but transform into something extraordinary when combined with heat and intention. The key is sourcing the best quality produce you can find—January's farmers' markets may seem sparse, but what they lack in variety, they make up for in concentrated flavor.

Fresh baby spinach forms the tender base of this salad. Look for leaves that are vibrant green without any yellowing or slimy spots. The baby variety is essential here—mature spinach can become tough and stringy when heated. If you can only find regular spinach, remove the thick stems and tear the leaves into bite-sized pieces. Pre-washed spinach works perfectly, but give it an extra rinse and thorough drying in a salad spinner.

Lacinato kale (also called dinosaur or Tuscan kale) is my preferred variety for this preparation. Its long, dark leaves have a slightly sweeter, more delicate flavor than curly kale, and the texture becomes silky rather than tough when warmed. When selecting kale, avoid bunches with yellowing or wilted leaves—the freshest kale will have crisp, perky leaves that snap rather than bend.

Winter citrus is the star that brightens this entire dish. Blood oranges provide stunning color and berry-like sweetness, while ruby red grapefruit adds beautiful pink segments and a pleasant bitterness that balances the rich nuts. Cara Cara oranges offer a lovely coral color and exceptionally sweet flavor. Choose citrus that feels heavy for its size—this indicates juiciness—and have smooth, firm skin without soft spots.

Mixed toasted nuts create the addictive crunch factor. I use a combination of pistachios for their vibrant green color and buttery flavor, along with sliced almonds for their delicate crunch. The nuts aren't just a garnish—they provide healthy fats, protein, and that crucial textural contrast that elevates this from simple sautéed greens to crave-worthy salad.

How to Make Warm Spinach and Kale Salad with Citrus and Toasted Nuts for January

Toast the nuts first

Heat a large, dry skillet over medium heat. Add 1/3 cup shelled pistachios and 1/4 cup sliced almonds. Toast for 3-4 minutes, stirring frequently, until the almonds are golden and fragrant. Watch carefully—nuts go from perfectly toasted to burnt quickly. Transfer to a plate to stop cooking and set aside.

Prep your citrus supremes

Using a sharp knife, cut the top and bottom from 2 blood oranges and 1 ruby grapefruit. Stand the fruit on a cut end and carefully slice away the peel and pith, following the curve of the fruit. Hold the peeled fruit in your hand and cut between the membranes to release perfect segments. Do this over a bowl to catch the juice—you'll need 2 tablespoons for the dressing.

Prepare the greens

Wash 4 cups baby spinach and 1 large bunch lacinato kale. For the kale, strip the leaves from the tough stems (save stems for stock). Stack the leaves, roll them into a cigar shape, and slice into 1/2-inch ribbons. You'll need about 6 cups loosely packed kale. Thoroughly dry both greens using a salad spinner—excess water will make the salad soggy.

Create the warm dressing base

In the same skillet (no need to clean), heat 2 tablespoons extra-virgin olive oil over medium heat. Add 2 minced shallots and cook for 2 minutes until softened. Add 2 minced garlic cloves and cook for 30 seconds more. Pour in the reserved citrus juice, 1 tablespoon honey, and 1 tablespoon white wine vinegar. Season with 1/2 teaspoon salt and 1/4 teaspoon freshly ground black pepper.

Wilt the kale first

Add the kale to the skillet with the warm dressing. Toss using tongs for 2-3 minutes until the kale turns bright green and wilts slightly but still has texture. The heat helps break down the tough cell walls, making the kale more tender and easier to digest. Don't overcook—you want it to retain some bite.

Add spinach and finish

Add the spinach to the skillet and toss for just 30-45 seconds until it begins to wilt. The spinach cooks much faster than kale, so watch carefully. Remove from heat immediately and transfer to a serving bowl. The residual heat will continue wilting the greens slightly.

Assemble and garnish

Gently fold in the citrus segments, being careful not to break them. Sprinkle the toasted nuts over the top, followed by 2 tablespoons crumbled goat cheese if desired. Finish with a light drizzle of good olive oil and an extra crack of black pepper. Serve immediately while still warm.

Expert Tips

Control the heat

Medium heat is crucial—too high and the garlic will burn, too low and the greens will stew rather than wilt. Test by holding your hand 6 inches above the pan; you should feel steady heat without it being uncomfortable.

Dry greens completely

Water on the greens will create steam, making them soggy instead of lightly wilted. Use a salad spinner, then lay on clean kitchen towels and pat dry. This extra step makes all the difference.

Time your assembly

Have everything prepped before you start cooking. The actual cooking happens fast—about 5 minutes total. This isn't a dish you can walk away from, but the results are worth the attention.

Season at every stage

Season the dressing, season the greens as they cook, and taste before serving. The difference between good and great often comes down to proper seasoning throughout the process.

Toast nuts ahead

Toast a big batch of mixed nuts on Sunday and store in an airtight container. They'll stay crisp for a week and make throwing this salad together even faster on busy weeknights.

Massage tough kale

If your kale seems particularly tough, massage it with a teaspoon of olive oil and pinch of salt for 30 seconds before cooking. This breaks down fibers and ensures tender results.

Variations to Try

Protein-Packed Version

Top with sliced grilled chicken, seared scallops, or a soft-boiled egg. The warm greens create a perfect bed for proteins, making this a complete meal.

Grain Bowl Style

Serve over a bed of warm farro or quinoa. The grains soak up the citrus dressing beautifully and add satisfying heft for hungrier days.

Asian-Inspired Twist

Replace olive oil with toasted sesame oil, add ginger to the dressing, and top with sesame seeds and crispy shallots. Use mandarin oranges for the citrus.

Mediterranean Version

Add Kalamata olives, sun-dried tomatoes, and crumbled feta. Replace honey with maple syrup and add fresh oregano to the dressing.

Spicy Kick

Add a pinch of red pepper flakes to the dressing or a drizzle of chili crisp oil. The heat pairs beautifully with the sweet citrus and earthy greens.

Nut-Free Option

Replace nuts with toasted pumpkin seeds or sunflower seeds. They provide similar crunch and nutrition while being allergy-friendly.

Storage Tips

This salad is best enjoyed immediately while still warm, but life doesn't always accommodate our culinary timing. If you must store leftovers, here's how to maintain the best possible quality:

For short-term storage (up to 24 hours), let the salad cool completely, then store in an airtight container in the refrigerator. The greens will continue to wilt and the nuts will lose their crunch, but the flavors will still be good. To revive, briefly microwave for 15-20 seconds just to take the chill off, then add fresh toasted nuts.

Component prep is the smarter approach for busy weeks. Wash and dry your greens, storing them in a paper towel-lined container for up to 4 days. Toast the nuts and store in an airtight container at room temperature for up to a week. Segment the citrus and store in its juice in the refrigerator for up to 3 days. When ready to serve, simply warm the dressing, wilt the greens, and assemble.

The dressing can be made entirely ahead and stored in the refrigerator for up to 5 days. Bring to room temperature or gently warm before using—olive oil solidifies when cold.

Frequently Asked Questions

Absolutely! Bagged baby spinach works perfectly for this recipe. Give it an extra rinse and thorough drying in a salad spinner. The convenience factor makes this salad realistic for busy weeknights, and the tender leaves wilt beautifully.

The heat helps tame kale's natural bitterness, but choosing the right variety is key. Lacinato kale is naturally less bitter than curly kale. Also, make sure to remove all the tough stems and don't overcook—overcooked kale becomes more bitter. A drizzle of honey in the dressing balances any remaining bitterness.

Yes! Simply omit the goat cheese or substitute with nutritional yeast for a cheesy flavor. Replace honey with maple syrup or agave. The salad is naturally dairy-free and can easily be made entirely plant-based while maintaining all its satisfying qualities.

Any winter citrus works beautifully. Regular navel oranges, Cara Cara oranges, ruby grapefruit, or even a mix of varieties. The key is using peak-season citrus when they're at their sweetest and most flavorful. Taste your citrus first and adjust the honey in the dressing accordingly.

Yes, but cook in batches. Overcrowding the pan will steam rather than wilt the greens. For more than 4 servings, use two large skillets or cook the greens in batches, keeping the first batch warm in a low oven while you cook the second. The assembly happens quickly at the end.

Humidity is the enemy of crispy nuts. Store toasted nuts in an airtight container at room temperature, not in the refrigerator. If they've softened, spread on a baking sheet and toast at 350°F for 5-7 minutes to restore their crunch. Always add them just before serving to prevent them from absorbing moisture from the salad.
