How to Cook Frozen Yellow Squash in the Oven

Learning how to cook frozen yellow squash in the oven comes down to a few simple steps, and once you’ve done it a couple of times, you’ll never look back.
 
Here’s the basic method broken down.
 

1. Preheat Your Oven to 425°F

A hot oven is your best friend when you cook frozen yellow squash in the oven.
 
High heat helps evaporate the excess moisture that frozen squash releases as it thaws.
 
If your oven runs cool, bump it to 450°F so the squash roasts instead of steaming.
 

2. Line a Baking Sheet With Parchment

Grab a large rimmed baking sheet and line it with parchment paper or foil.
 
This keeps the squash from sticking and makes cleanup a breeze.
 
Whatever you do, don’t crowd the pan when you cook frozen yellow squash in the oven.
 
If the pieces are touching, they’ll steam each other instead of roasting.
 

3. Toss the Frozen Squash With Oil and Seasoning

Drizzle the frozen slices with a couple of tablespoons of olive oil and toss them right on the baking sheet.
 
You can also add salt, black pepper, garlic powder, onion powder, or smoked paprika.
 
A little grated parmesan or a squeeze of lemon at the end takes it to another level.
 

4. Spread Them in a Single Layer

Spread the seasoned squash out into one even layer with a little space between each piece.
 
This is the step most people skip, and it’s the reason their squash turns out mushy.
 
When you cook frozen yellow squash in the oven the right way, the edges get golden and slightly crisp.
 

5. Roast for 25 to 35 Minutes

Slide the pan into the oven and roast for about 25 to 35 minutes, flipping halfway through.
 
The squash is done when it’s fork-tender and the edges are browned.
 
If you like a deeper roast, give it another five minutes and keep an eye on it.
 

Tips for the Best Frozen Yellow Squash in the Oven

Want to know how to cook frozen yellow squash in the oven like a pro?
 
These little tricks make a big difference.
 

1. Don’t Thaw Before Roasting

You really can cook frozen yellow squash in the oven straight from the freezer.
 
Thawing ahead of time just leaves you with watery squash that steams instead of roasts.
 
Trust the process and let the hot oven do the work.
 

2. Pat Away Excess Moisture

If your frozen squash has a lot of ice crystals, blot it with a paper towel after the first ten minutes.
 
This helps the edges crisp up as you cook frozen yellow squash in the oven.
 

3. Use High Heat and a Hot Pan

Preheating the baking sheet for a few minutes gives the squash a head start on browning.
 
A screaming hot pan plus a hot oven equals caramelized, not soggy, results.
 

4. Add a Finishing Touch

Once your squash is out of the oven, finish with fresh herbs, a pat of butter, or a sprinkle of parmesan.
 
A squeeze of lemon brightens everything up.
