Toaster Oven Acorn Squash

Nutty and sweet, Toaster Oven Acorn Squash makes a fantastic fall side dish. Earthy acorn squash halves are coated with oil, seasoned, and roasted until tender.

Roasted squash is one of the best parts of fall but have you ever tried to cut a raw squash?

Hard squashes like butternut and spaghetti squash are kind of terrifying to cut.

If you’ve ever chased one around your cutting board, repeatedly getting your knife stuck in it. Then you know what I’m talking about.

That’s one of the reasons I LOVE acorn squash. It has a rind/skin that’s much thinner, so it’s easier to slice and cook.

Hands down the perfect squash for cooking in your little toaster oven is delicata squash. But acorn squash is a close second for sure.

The squash’s small size means it’s easy to fit in most toaster ovens. Usually, I can cook one acorn squash in our little Oster and two in our larger Breville Smart Oven Pro (BOV845BSS).

Stuffed with vegetarian chili, baked macaroni and cheese, or yogurt with cinnamon these fun squash bowls make a healthy and satisfying vegetarian meal for two.

How to Cut an Acorn Squash Into Bowls

  1. Place your squash on a cutting board and slice in half lengthwise (for longer ‘acorn” shaped bowls) or widthwise (for round “flower” shaped bowls).
  2. If the squash is rolling around slice a small portion off of the bottom of the squash to provide a flat base to rest it on before slicing.
  3. Scoop out the seeds using a spoon or ice cream scoop.

Coconut oil and cinnamon are nice if you’re planning to fill your acorn squash with fruit and yogurt. To make them sweeter, flip the squash over 20 minutes into the cooking time and sprinkle with brown sugar or drizzle with maple syrup.

  1. Thank you so much for this recipe. I roasted two acorn squashes today, one with za’atar and one with fresh thyme, and all four halves had 2-3 garlic cloves tucked under. My filling was sauteed celery, red bell pepper, leftover rice, salt, and pepper. It was fantastic.

    1. Yum! From the seasonings to the filling, everything sounds delicious, Megan.

      I love the addition of the garlic cloves and can’t wait to try it with our next squash. Do you peel the cloves before or after roasting?

    1. Thanks Rachel! I think it might actually be easier to cook squash this way since the toaster oven preheats in 2 or 3 minutes and then you are ready to get your squash roast on 🙂
