This squash is outstanding as a side dish, but you can also top it with canned tuna to create a simple, healthy main dish. It's easy and so tasty! I like to use my own canned tomatoes for the best flavor. —Carol Chase, Sioux City, Iowa


Test Kitchen tips
  • If you like cheesy goodness, top the squash mixture with cheese during the last 15 minutes of cooking, giving it time to get melty.
  • Adding the tomato mixture after cooking the squash allows you to discard any condensed liquid from the slow cooker before combining all the ingredients.

    Yield: 6 servings
    Prep: 15 min
    Cook: 5 hours 15 min

    Ingredients

    • 1 medium spaghetti squash (about 4 pounds), halved, seeds removed
    • 1/4 cup sliced green olives with pimientos, drained
    • 1 can (14 ounces) diced tomatoes

    • 1/2 cup shredded cheddar cheese
    • 1/4 cup chopped fresh basil

    1. Place squash in a 6- or 7-quart slow cooker, overlapping as needed to fit. Cook, covered, on low until tender, 5-7 hours.
