Spring Mix
Spring mix (also called mesclun or spring greens) is a pre-combined blend of young, tender salad leaves, typically baby lettuces, arugula, frisee, radicchio, spinach, and mizuna, harvested while small for a mild, slightly peppery flavor and soft texture. It's sold pre-washed in bags or clamshells and used raw as a salad base rather than cooked.
Varieties
"Spring mix" and "mesclun" are used almost interchangeably in the US, though mesclun traditionally refers to a specific French mix of young lettuces and herbs; American spring mix blends vary by producer and season, so the exact ratio of arugula, radicchio, and lettuces in a bag will differ from batch to batch.
Buying tips
Check the bag date and look through the clear side for wilted, yellowing, or slimy leaves before buying. Loose (bulk bin) spring mix lets you smell for any sour or fermented odor, a sign it's turning; bagged mix should feel light and dry, not damp or clumped together.
Substitutes
Baby spinach — 1:1
Milder and less peppery, with a slightly heavier leaf; works well as a base but lacks the bitter and pepper notes of true spring mix.
Arugula, chopped romaine, and radicchio (homemade blend) — 1:1 by volume, roughly 2 parts romaine to 1 part arugula to 1 part radicchio
Closest homemade approximation to store-bought spring mix; adjust ratios toward more arugula for a peppery bite or more romaine for crunch.
Mixed baby kale and spinach — 1:1
Sturdier and more nutrient-dense, but tougher and more bitter; massage briefly with a bit of oil to soften before serving raw.
Butter lettuce, torn — 1:1
Much milder and softer with no bitterness or pepper, but a fine stand-in when only delicacy of texture matters.
Storage
Keep spring mix in its original bag or a container lined with a dry paper towel in the refrigerator crisper drawer, ideally around 34-38\u00b0F. Press out excess air from bags before sealing. It generally holds for 4-6 days from purchase; any sliminess or dark, wet spots on leaves means it's past use.
How to use
Use raw as a salad base, tossed with vinaigrette just before serving since dressed leaves wilt within 20-30 minutes. Also works as a bed under warm proteins like grilled chicken or seared salmon (the residual heat wilts it slightly, which is fine), piled onto sandwiches and burgers, or stirred into pasta at the very end of cooking to wilt briefly.
What it pairs with
Pairs well with acidic vinaigrettes (lemon, sherry, or balsamic), soft cheeses like goat cheese or feta, toasted nuts, and sweet elements like dried cranberries or sliced pear that balance the mix's bitter and peppery notes.
Nutrition
Because it's a blend of leafy greens, spring mix is low in calories (about 5-10 per cup) and provides vitamin K, vitamin A, and folate; the exact nutrient mix varies with which greens dominate a given batch.
FAQ
Is spring mix the same as mixed greens?
Not always. "Mixed greens" is a broader label that can include sturdier greens like kale or chard, while spring mix specifically refers to young, tender baby lettuces and salad greens harvested small.
Why does spring mix wilt so much faster than romaine or iceberg?
The leaves are harvested young and thin-walled with a high water content and delicate cell structure, so they lose crispness and bruise much faster than mature, thicker-leaved lettuces.
Can you cook spring mix instead of eating it raw?
Yes, it wilts quickly like spinach; add it to hot pasta, soup, or a saute in the last 30-60 seconds of cooking so it just softens without turning mushy or bitter.
Do you need to wash pre-washed spring mix again?
Most home cooks skip it since commercial washing lines rinse and sanitize the leaves, but a quick rinse and spin-dry is a reasonable extra step if the bag has been open a few days.
