How to Make It

Step 1

Melt butter with oil in a 12-inch ovenproof skillet over medium-high heat; add zucchini and onion, and sauté 12 to 14 minutes or until onion is tender. Remove from heat, and stir in 1/4 cup grated Parmesan cheese.

Step 2

Whisk together eggs and next 3 ingredients at least 1 minute or until well blended. Pour over vegetable mixture.

Step 3

Bake at 350° for 13 to 15 minutes or until set; increase oven temperature to broil, and broil 5 1/2 inches from heat 1 to 2 minutes or until edges are lightly browned. Sprinkle evenly with remaining 1/4 cup grated Parmesan cheese and basil. Garnish, if desired.

Step 4

Lightened Zucchini-Onion Frittata: Reduce butter to 1 tablespoon, and omit oil. Sauté zucchini and onion as directed; remove from heat. Reduce grated Parmesan cheese to 1/4 cup, stirring 2 tablespoons into vegetable mixture. Substitute 1 (15-ounce) carton garden vegetable egg substitute for 8 eggs and 1/4 cup lowfat milk for 1/4 cup milk, and whisk together with salt and pepper. Pour over vegetable mixture. Bake as directed; do not broil. Sprinkle evenly with remaining 2 tablespoons grated Parmesan cheese and basil. Garnish, if desired.

This was excellent. I made a few changes: I used 4 eggs and 3/4 cup egg whites, and reduced butter to 1 Tbsp. and oil to 1/2 Tbsp. The end result was great and I highly recommend it.

This recipe is a throw together, fast meal, and even the kids love it! You could make it for breakfast, lunch, or dinner and it would still taste good! You could make it for a fancy meal or an everyday meal.

My wife is usually a real downer when it comes to trying new things. But this dish she loved. Used egg substitute.
