Can I make this dish ahead of time?
Yes. Prepare the baked feta and tomato mixture up to 2 days ahead and store in an airtight container in the refrigerator. Reheat gently on the stovetop with a splash of pasta water before tossing with freshly cooked pasta.
What type of feta cheese works best?
Blocks of full-fat, brined feta cheese yield the creamiest results. Crumbled feta will break apart during baking and won't create the same sauce consistency.
Can I use a different pasta shape?
Yes. Any short or medium pasta shape works—penne, rigatoni, or farfalle are good alternatives to casarecce. Avoid thin, long pasta like spaghetti, which won't hold the creamy sauce as well.
How do I know when the feta is done baking?
The feta should soften and begin to collapse slightly, and the tomatoes should start to blister and release their juices, typically 25–30 minutes at 400°F.
Can I substitute the cherry tomatoes?
Grape tomatoes work well as a 1:1 swap. Halved regular tomatoes can work but may release more liquid; drain excess before tossing with pasta.
