I love this eggplant and squash tian because it’s a simple way to enjoy fresh vegetables that taste amazing when baked together. It’s one of those dishes that feels cozy and healthy at the same time, perfect for any day you want something light but satisfying. I can’t wait for you to try it and see how the flavors blend so nicely!
Most of the ingredients in this recipe are easy to find at your local supermarket. Eggplant, zucchini, yellow squash, and onions are common vegetables, but if you haven’t cooked with yellow squash before, it’s similar to zucchini but a little sweeter. Parmesan cheese is a great topping that adds a nice salty flavor, and you can usually find it in the dairy or cheese section. Olive oil, garlic, salt, and pepper are pantry staples that bring everything together.

Ingredients for Eggplant And Squash Tian Recipe
Eggplant: A large vegetable with a slightly spongy texture that softens when cooked and absorbs flavors well.
Zucchini: A green summer squash that is mild in flavor and cooks quickly.
Yellow squash: Similar to zucchini but with a slightly sweeter taste and bright yellow skin.
Onion: Adds a savory and slightly sweet flavor when baked.
Garlic: Minced cloves bring a strong, aromatic flavor that enhances the dish.
Olive oil: Used to drizzle over the vegetables, adding richness and helping them roast nicely.
Salt: Seasoning that brings out the natural flavors of the vegetables.
Black pepper: Adds a mild heat and depth to the dish.
Parmesan cheese: Grated cheese that melts on top, giving a golden, savory finish.
Technique Tip for This Recipe
One of the most helpful moves in this Eggplant And Squash Tian Recipe is slicing the vegetables thinly and evenly. It might seem simple, but getting those slices just right makes a big difference in how the dish cooks and tastes. Here’s how you can do it step by step:
- Start by washing your eggplant, zucchini, yellow squash, and onion so they’re clean and ready.
- Use a sharp knife or a mandoline slicer if you have one. A sharp knife helps you cut smoothly without squishing the veggies.
- Hold the vegetable steady on a cutting board. If it’s round, like the zucchini or eggplant, you can slice a small piece off one side to make a flat surface so it doesn’t roll.
- Slice the veggies into thin, even rounds—about ⅛ inch thick. Try to keep each slice the same thickness so they cook evenly.
- For the onion, peel off the skin first, then slice it into thin rings or half-rings, depending on your preference.
Slicing evenly helps the vegetables cook at the same speed, so you don’t end up with some pieces mushy and others still crunchy. It also makes the layers look prettier when you arrange them in the baking dish. Plus, thin slices soften nicely and soak up the olive oil and garlic flavors better.
I remember the first time I tried this, I cut the eggplant too thick, and it took forever to get tender. After that, I made sure to take my time slicing, and it really made the whole dish come together faster and taste better. If you’re in a hurry, a mandoline slicer is a great shortcut—it gives you perfect slices in no time!

How to Store or Freeze This Dish
Allow the eggplant and squash tian to cool completely at room temperature before storing. This helps prevent condensation, which can make the dish soggy.
Transfer the cooled vegetable tian to an airtight container. If you don't have a container large enough, you can use a baking dish covered tightly with plastic wrap or aluminum foil.
Store the container in the refrigerator. The tian will keep well for up to 3-4 days.
When ready to reheat, preheat your oven to 350°F (175°C). Place the tian in an oven-safe dish and cover with aluminum foil to prevent it from drying out. Heat for about 15-20 minutes, or until warmed through.
For freezing, first ensure the tian is completely cooled. This prevents ice crystals from forming, which can affect the texture.
Wrap the tian tightly in plastic wrap, then again in aluminum foil. This double wrapping helps protect against freezer burn.
Place the wrapped tian in a freezer-safe bag or container. Label with the date to keep track of its freshness. The tian can be frozen for up to 2-3 months.
To reheat from frozen, remove the tian from the freezer and let it thaw in the refrigerator overnight. Once thawed, follow the same reheating instructions as above.
If you’re in a hurry, you can reheat the tian directly from frozen. Preheat your oven to 350°F (175°C), cover the tian with aluminum foil, and bake for about 30-40 minutes, or until heated through. Remove the foil for the last 10 minutes to allow the top to crisp up.
How to Reheat Leftovers
Oven Method: Preheat your oven to 350°F (175°C). Place the leftover tian in an oven-safe dish. Cover with aluminum foil to prevent drying out. Heat for about 15-20 minutes, or until the vegetables are warmed through. Remove the foil for the last 5 minutes to allow the parmesan cheese to get crispy again.
Microwave Method: Transfer a portion of the tian to a microwave-safe plate. Cover with a microwave-safe lid or another plate to retain moisture. Heat on medium power for 2-3 minutes, checking halfway through to ensure even heating. Be careful not to overcook, as the vegetables can become mushy.
Stovetop Method: Heat a non-stick skillet over medium heat. Add a small amount of olive oil to the pan. Place the leftover tian in the skillet and cover with a lid. Heat for 5-7 minutes, stirring occasionally, until the vegetables are warmed through. This method helps retain some of the original texture.
Air Fryer Method: Preheat your air fryer to 350°F (175°C). Place the leftover tian in the air fryer basket in a single layer. Heat for 5-7 minutes, shaking the basket halfway through to ensure even heating. This method can help restore some of the crispiness to the parmesan cheese topping.
