Spinach Salad with Warm Mushrooms, Garlic and Sherry
A Spanish-inspired warm salad where tender fresh spinach meets a sizzling pan of golden mushrooms and garlic, all brought together with a bright sherry vinegar dressing. The warmth of the pan wilts the spinach just slightly while keeping it vibrant and fresh, creating a delicate balance of textures. Perfect as a light side dish or starter.
Steps
Before you start
- Pat the spinach completely dry after washing—moisture prevents crisp greens
- Slice the mushrooms to a consistent thickness so they cook evenly
- Have all ingredients prepped and within arm's reach since the cooking happens quickly
Arrange the spinach
- Place the washed and dried spinach in a large salad bowl or on a serving platter, spreading it into an even layer.
- Set aside.

Tip: Completely dry spinach will not wilt excessively and will stay more vibrant when the warm mushroom mixture hits it.
Heat the oil and start mushrooms
- Pour 4 tablespoons (60 ml) of the olive oil into a large 12-inch (30 cm) skillet over medium-high heat.
- Once the oil is shimmering (about 1 minute), add all the sliced mushrooms in a single, slightly crowded layer.
- Do not stir for 3–4 minutes so the bottoms develop a light golden color.

Ready when: Mushroom bottoms are golden brown with light moisture still visible on top
Tip: Resist the urge to stir; mushrooms release moisture when crowded and stirred, preventing browning. One layer and patience yields better texture.
Toss and continue cooking
- Stir the mushrooms and continue cooking for 1–2 minutes more until they release their liquid and it begins to evaporate, keeping the pan on medium-high heat.
- The mushrooms should be tender and lightly caramelized.

Ready when: Mushrooms are tender with light caramelization; most liquid has evaporated from the pan
Tip: If liquid still pools, give it another 30 seconds—excess moisture will cool the vinegar and dilute the flavor.
Add garlic and finish cooking
- Add the minced garlic and the remaining 1 tablespoon (15 ml) of olive oil to the pan, stirring constantly for about 1 minute until the garlic is fragrant but not browned.
- It should smell sweet and toasted.

Ready when: Garlic is fragrant and light golden, coating the mushrooms evenly
Tip: Keep the heat at medium-high and stir constantly—garlic burns quickly and becomes bitter. You want toasted, not charred.
Deglaze with vinegar
- Pour the sherry vinegar into the hot pan while stirring.
- It will sizzle and steam briefly.
- Continue stirring for 30 seconds to lift any flavorful browned bits from the bottom of the pan (called the fond) and coat the mushrooms evenly.

Ready when: Vinegar has reduced slightly and mushrooms are coated with a glossy mixture; fond is scraped from the pan bottom
Tip: The vinegar adds brightness and acidity to balance the earthiness of the mushrooms. Scrape the pan bottom to release all the flavor.
Season and pour over spinach
- Taste the mushroom mixture and season with kosher salt and freshly ground black pepper.
- Immediately pour the entire contents of the hot skillet (mushrooms, garlic, and pan juices) over the fresh spinach in the bowl or platter.
- The heat will gently wilt the spinach while keeping it bright and tender.

Ready when: Spinach is lightly wilted but still vibrant green; mushrooms and pan juices evenly distributed
Tip: Pour immediately while the pan contents are hot—this creates the perfect gentle wilt. Waiting lets everything cool and the spinach stays too crisp.
Toss gently and serve
- Toss the salad gently with tongs or two forks, being careful not to bruise the spinach leaves.
- Divide among four plates or serving bowls.
- If desired, sprinkle a tiny pinch of red pepper flakes over each portion for a hint of heat.

Ready when: Salad is evenly combined with mushrooms distributed throughout
Tip: Toss gently to preserve the tender leaves. Aggressive tossing bruises spinach and makes it look dull and wet.
Good to know
Tips
- For a richer salad, add a poached or soft-boiled egg on top or scatter crispy pancetta or jamón serrano over each plate.
- This salad pairs beautifully with crusty bread to soak up the pan juices—have some available for serving.
- If you prefer the spinach less wilted, use fewer mushrooms or remove the pan from heat 30 seconds before pouring to let it cool slightly.
- Toast a handful of sliced almonds or pine nuts separately and scatter them on top just before serving for added texture and richness.
Make ahead
The spinach can be washed and dried up to 4 hours ahead and stored in a sealed container in the refrigerator. Prep the mushrooms and garlic up to 2 hours ahead. The salad itself must be assembled and served immediately—do not make ahead as the spinach will wilt too much and lose its vibrant texture.
Storage & reheating
Leftovers will keep in the refrigerator for up to 1 day in an airtight container, though the spinach will become quite soft. Reheat gently in a skillet over medium heat until warm (about 2 minutes), stirring occasionally. Best enjoyed fresh and warm on the day it is made.
Substitutions
- cremini or button mushrooms → cremini and shiitake mushroom mix. Shiitakes add deeper, more complex umami flavor. Use 6 oz cremini and 6 oz shiitake, both sliced ¼ inch thick.
- sherry vinegar → red wine vinegar or aged balsamic vinegar. Red wine vinegar is sharper and more assertive; use the same amount. Balsamic is sweeter; reduce to 1½ tablespoons (22 ml) to avoid cloying.
- fresh baby spinach → arugula or a 50/50 mix of spinach and arugula. Arugula brings a peppery bite. It wilts even faster, so work very quickly. The mixed green combination adds complexity.
- garlic → shallots, minced. Use 2 medium shallots (about 2 oz / 60 g) for a softer, sweeter allium note instead of garlic's sharp bite.
