COOKING TIPS

In the kitchen.

1For a classic Caesar salad, use the crisp inner hearts which have a sweeter, more delicate flavor.
2Cut heads in half lengthwise, brush with olive oil, and grill or sear for 1-2 minutes per side for a smoky, wilted side dish.
3The sturdy, boat-shaped leaves are an excellent low-carb substitute for bread or tortillas, perfect for wraps and lettuce cups.
4Chop and add to soups or stir-fries in the last minute of cooking to add a slightly crunchy texture and nutrients without becoming mushy.

STORAGE

Keep it fresh.

Store whole, unwashed heads in a perforated plastic bag in the refrigerator's crisper drawer for up to 10 days.
To store washed and chopped leaves, dry them thoroughly and place them in a container lined with a paper towel to absorb moisture, keeping them crisp for 3-5 days.

FAQ

Frequently asked questions.

Is romaine lettuce keto-friendly?

Yes, romaine lettuce is very keto-friendly. With only about 3.3g of total carbohydrates per 100g, it can be used freely in low-carb diets as a salad base or even as a bread substitute for wraps.

What does romaine lettuce taste like?

Romaine has a mild, slightly sweet flavor compared to more bitter greens. It is most prized for its crunchy texture, particularly the thick center ribs of the leaves, which remain crisp even when lightly cooked.

Can you cook romaine lettuce?

While typically eaten raw, romaine is sturdy enough to be grilled, seared, or sautéed. Grilling halved romaine hearts for a few minutes adds a smoky char that pairs well with Caesar dressing while maintaining a crisp center.

How long does romaine lettuce last?

A whole head of romaine lettuce typically lasts between 7 to 10 days in the refrigerator if stored properly. Pre-cut or bagged romaine has a much shorter shelf life, usually lasting only 3 to 5 days after opening.

How do you know if romaine lettuce has gone bad?

Signs of spoilage include leaves that are slimy, limp, or have turned brown or black. If the lettuce has a pungent or sour odor, it should be discarded immediately.

Do I need to wash romaine lettuce?

Yes, you should always wash romaine lettuce to remove dirt, sand, and potential bacteria. Separate the leaves and rinse them thoroughly under cold running water, then dry them using a salad spinner or clean towels to ensure dressings adhere properly.
