Vegetables to add at the last minute

When you add vegetables to an already hot dish they require a shorter cooking or heating time versus when started in a cold slow cooker. Some of the best vegetables for slow cookers are ones that get added at the last minute to easy one-pot dinners. These vegetables can help long-cooking dishes finish on a fresh note and give your meals texture.

Fold these veggies into the slow cooker 5-10 minutes before dinner time. Cook on HIGH until everything is heated through.

  • Artichoke Hearts — Rinse, drain, and halve or quarter before adding to the slow cooker.

  • Bok Choy / Baby Bok Choy — Bok choy is quick cooking, healthy, and crunchy. Add bok choy or baby bok choy leaves to almost any Asian-inspired crock pot dish.

    • Slow Cooker Teriyaki Chicken with Bok Choy

  • Corn — Use fresh or frozen corn kernels for a burst of sweet flavor and color.

  • Greens — Fold tender baby spinach or other greens into slow cooker soups, curries, or pasta sauces at the last minute to up the nutritional value. Some will require a few more minutes of cooking.

  • Green Peas — Add fresh or frozen green peas to slow cooker curry dishes.

  • Hominy — Add to Slow Cooker Pozole or other soups near the end of cooking.

  • Mushrooms (sautéed) — If mushrooms cook too long in the slow cooker, the texture becomes rubbery. The best method is to sauté sliced mushrooms ahead of time and add them at the end of cooking. If a dish needs to cook with mushrooms for flavor, then use dried and rehydrated porcini mushrooms.

  • Snow Peas & Sugar Snap PeasMiso Chicken Soup

  • Tomatoes — Fresh or canned diced tomatoes work to give your dishes a burst of flavor.

Vegetables that take just a little longer

These veggies offer a fresh texture when added to hot slow cooker dishes about 15-30 minutes prior to eating. The longer they cook the softer they will be.

How do you not overcook vegetables in a slow cooker? ›

Slow cooker recipes have (obviously) long cook times, and it's the meat—not the carrots—that benefit from it. By placing the protein at the bottom (closest to the heating element), and vegetables at the top, you can keep your plant parts a little more toothsome, while ensuring your meat is fall-apart tender.

Why are my potatoes and carrots still hard in a slow cooker? ›

Insufficient Liquid: If there wasn't enough liquid in the crockpot, it could have caused uneven cooking. Potatoes need to be fully submerged in liquid to cook evenly. Old Potatoes: Very old or stored potatoes can become starchy and may not soften as well during cooking. It's best to use fresh, firm potatoes.

When to add carrots and celery to a slow cooker? ›

take a bite to test...they should have just a little crunch to them. Then add them for the last 30-45 minutes in the crock (cooking on high in this example). Microwaving vegetables is the best way to cook them as it is the quickest. The quicker you can cook vegetables, the more nutrients they maintain.

Which vegetables take the longest to cook? ›

Root vegetables like sweet potatoes, carrots and turnips take the longest, followed by hard squash and cruciferous vegetables like butternut squash, cauliflower and broccoli. Tender items like cherry tomatoes or zucchini come next, then cooking greens, which have the shortest roasting time.

When to add bell peppers to a slow cooker? ›

I add only part of the bell peppers in the beginning, which gives the tomato sauce and the chicken the flavor of peppers, but still keeps most of the bell peppers nice and crisp, since they are sort of steaming during the second part of the cooking process.

Do you put hot or cold water in a slow cooker when cooking? ›

Preheat the cooker and add hot liquids, if possible. Preheating the crock before adding ingredients or cooking on the highest setting for the first hour will ensure a rapid heat start and will shorten the time foods are in the temperature danger zone.

Is there anything you Cannot cook in a slow cooker? ›

The slow cooker is great for tenderizing tough cuts of meat, preparing a stew, or whipping up a rich, flavorful bowl of chili. It's not great, however, for cooking delicate vegetables such as spinach, asparagus, and peas.
