Tri-Color Summer Squash on the Grill

"If you're on a diet that forbids fried squash and you miss it you have to try this. If you're not on a special diet you'll want to try it anyway because its delicious. I allow 1-2 squash per person depending on size. Don't worry about having too much because the leftovers are good chopped into green salads or pasta salads or with Italian dressing (try Recipe #213989 ), as a snack. White patty pan squash can be hard to find if you don't grow them yourself, but the taste will be just as good with only 2 colors. You could use whole, baby squash, but the sizes I suggest -- where the seeds have begun to develop but have not yet begun to harden -- have more flavor. Note -- prep time does not include marinating time."

Ready In:


  • 3 zucchini (8-10 inches)
  • 3 yellow squash (8-10 inches)
  • 3 pattypan squash (6-7 inches diameter. I prefer the white variety)
  • 12 cup olive oil
  • 12 teaspoon garlic powder
  • 2 teaspoons italian seasoning
  • salt and pepper
  • grated parmesan cheese (optional)
  • horseradish sauce (optional)


  • Slice the squash lengthwise into slabs 1/2 to 3/4 inches thick.
  • Mix olive oil with seasonings. Toss with squash slabs and let sit at least 10 minutes and up to several hours (refrigerated or in picnic cooler).
  • Drain and reserve the marinade.
  • Grill in batches over medium-high heat.
  • Cook 3-5 minutes per side, brushing reserved marinade onto the top before turning. You want them to brown quickly without becoming mushy but you don't want them to scorch.
  • Salt and pepper to taste.
  • Pass grated parmesan and/or horseradish sauce (1 tsp to 1 tbs horseradish -- horseradish fades as it ages so how much depends on how long the jar has been open -- blended into 1/2 cup sour cream), at the table.

    Great grilled vegies! The Italian seasoning really gave this a nice flavor. I could not find pattypan, so added some grilled red bell pepper. I will keep my eyes open for the pattypan at the farmer's market and try it next time!
