I never thought I’d become obsessed with microwaved vegetables, but here we are! This simple yellow squash recipe has been my go-to weeknight side dish because it takes less than 10 minutes and only needs a handful of ingredients like fresh squash, butter, and some garlic powder. It’s proof that you don’t need to turn on your oven to make something genuinely delicious.

Ingredients
- 2 medium yellow squash (sliced into 1/2-inch thick rounds)
- 1/2 yellow onion (thinly sliced into half-moons)
- 1/4 cup water
- 1/2 tsp kosher salt
- 1/4 tsp freshly cracked black pepper
- 1/2 tsp garlic powder
- 1/2 tsp dried Italian seasoning
- 1 tbsp unsalted butter
- 1/8 tsp crushed red pepper flakes
Step 1: Prepare and Season the Squash and Onions
- 2 medium yellow squash, sliced into 1/2-inch rounds
- 1/2 yellow onion, thinly sliced
- 1/4 cup water
- 1/2 tsp kosher salt
- 1/4 tsp freshly cracked black pepper
- 1/2 tsp garlic powder
- 1/2 tsp dried Italian seasoning
- 1/8 tsp crushed red pepper flakes
Slice the yellow squash into 1/2-inch thick rounds and thinly slice the yellow onion into half-moons.
In a microwave-safe bowl, combine the squash and onion slices.
Add the water, kosher salt, black pepper, garlic powder, Italian seasoning, and crushed red pepper flakes.
Toss everything together so the seasonings are evenly distributed throughout the vegetables.
I like to season before microwaving rather than after—it allows the flavors to infuse into the squash as it cooks rather than just sitting on the surface.
Step 2: Microwave and Finish
- seasoned squash and onion mixture from Step 1
- 1 tbsp unsalted butter
Cover the bowl with a microwave-safe lid or plate and microwave on high for 3 to 4 minutes, until the squash is tender and slightly softened but still holds its shape.
Carefully remove the bowl from the microwave (it will be hot) and drain any excess water using a colander or by carefully pouring it off.
Add the butter to the warm squash and onion mixture and gently toss until the butter melts and coats all the vegetables.
Serve immediately while still warm.
