1large sweet yellow onion cut in half and sliced
2russet or red potatoesscrubbed, unpeeled, and thinly sliced
2yellow squashthinly sliced
2large ripe tomatoesseeded and thinly sliced (optional
½cupgrated Parmesan cheese
Salt and pepper to taste
In a large skillet over medium heat, heat 1 tablespoon olive oil.
Once the olive oil is hot, add onions and saute until tender, about 6 minutes.
Add the garlic to the skillet and saute for an additional minute until fragrant. Remove from heat.
Spread the onion mixture in the bottom of an 8 or 9 inch baking dish. (I just use my standard 9-inch pie dish).
Layer potato slices, zucchini slices, and squash slices (and tomato if you're using them) alternately on top of onion mixture in baking dish. Fit them tightly into a spiral pattern in a single layer in the dish. (Depending on how large the vegetable were, you may have extra.)
Season with salt and pepper.
Drizzle with 1 tablespoon olive oil.
Cover and bake at 375° for about 35 minutes.
Uncover and sprinkle Parmesan on top. Bake for an additional 15-25 minutes or until the cheese is melted and slightly browned.
Be sure your vegetables are thinly sliced to about ⅛- inch thick so that they'll cook all the way through.
