Spaghetti squash is not only gluten-free, nutrient-dense, and low in carbs, but it’s an incredibly versatile food to cook with, and there are multiple ways to prepare it.

While cutting a spaghetti squash may be intimidating, cooking it is relatively simple, as long as you have the right tools and follow the expert-approved instructions below. Here’s how to cut a spaghetti squash, and then bake it or microwave it, depending on your preference.

Cutting a spaghetti squash may feel like an overwhelming task given its sheer size and tough exterior. The following tips from Jason Hawk, chef-instructor at the Institute of Culinary Education, will help you to cut this vegetable safely.

1. Use a sharp knife. Cutting with a heavy, large knife, such as a chef’s knife, will give you the ideal amount of control.

2. Use a flat, steady surface. Laying a damp cloth underneath a cutting board can stop it from slipping.

3. Slice off the ends. Removing the ends ensures that the squash is less likely to roll while you’re cutting it, says Hawk.

4. Carefully cut the squash in half. . Position the knife to cut the squash down the middle, from the top to bottom. Once the knife is inside the squash, you can use the weight of the knife to apply gentle pressure as you make one long cut.

5. Scoop out the seeds. Use a spoon to scrape all of the seeds out.

Alternate method: In the microwave

Cooking your spaghetti squash in the microwave can cut down on cooking time, but Hawk warns you may compromise on taste.

If you want to microwave your squash because you’re short on time:

1. Prick the squash all over with a fork. Poking holes in the skin will allow steam to escape and heat to penetrate the thick skin more easily.

2. Place squash cut-side down in a microwave-safe baking dish.

3. Fill the dish with about an inch of water.

4. Cover the baking dish with a microwave-safe lid.

5. Microwave on high for 10 to 15 minutes until fork-tender. Remember to use pot holders when removing the baking dish from the microwave. The strands should pull apart effortlessly, and have the texture of al dente pasta.

If you have a small microwave or are cooking a large squash, you may need to cook the halves separately. In that case, aim for about 10 minutes per half.

How to pick a spaghetti squash

Spaghetti squash in season from early fall through the winter, peaking in October and November, according to Hawk.

A spaghetti squash is usually ready to be cooked if it’s turned a deep golden yellow color, says Hawk. To test the ripeness, you can also try pushing your fingernail into the skin: a mature squash will have developed a tough exterior, making it harder to puncture. If your fingernail penetrates the skin easily, it likely needs more time to ripen.

How to use spaghetti squash

Spaghetti squash is a popular pasta substitute thanks to its noodle-like structure, but there are many other ways to use this vegetable. Fluff up the strands and use the whole half as the base of a burrito bowl. Griddle the cooked strands until crispy like hash browns. Add it into muffins or quick breads a la zucchini bread. Use it in stews, chili, salads, or frittatas. Cook it down with milk to make a breakfast porridge.

Hawk’s favorite way to use spaghetti squash is in a casserole, which you can customize with your preferred vegetables, legumes, meats, seasonings, and sauces. “It gives a pleasant texture as well as a sweet, nutty flavor when weaved through the dish,” he says.

Insider’s takeaway

Spaghetti squash is versatile enough to be used in a wide variety of dishes and can be cooked both in the oven and the microwave.

To cut a squash safely, consider using a chef’s knife (or something comparable), laying a damp towel underneath your cutting board, and removing the ends first.

While baking spaghetti squash will enhance the flavor more, microwaving it can take significantly less time.
