- 3 tablespoons olive oil (plus extra for greasing the pan)

Perfect Pairings: Serving Suggestions
This Eggplant & Squash Tian shines as a main dish or a hearty side. For a complete meal, pair it with a crisp green salad dressed with lemon vinaigrette or a slice of crusty bread to soak up the creamy custard. If you’re serving it as a side, it complements grilled chicken or roasted lamb beautifully. Pro tip: Garnish with extra fresh basil or a sprinkle of parmesan for a finishing touch!
Make It Your Own: Recipe Variations
Feel free to customize this tian to suit your taste or pantry. Swap zucchini for pattypan squash, or add layers of thinly sliced potatoes for extra heartiness. For a dairy-free version, replace the cream with coconut milk and use a plant-based cheese alternative. Experiment with herbs like thyme or oregano for a different flavor profile. The possibilities are endless!
Time-Saving Tips for Busy Cooks
To streamline prep, slice all your vegetables in advance and store them in the fridge until ready to use. You can also skip browning the eggplant if you’re short on time—just layer it raw for a quicker assembly. Bonus tip: Use a mandoline slicer for perfectly even vegetable slices in minutes!
Storage and Reheating Made Easy
Leftovers? No problem! Store the tian in an airtight container in the fridge for up to 3 days. Reheat individual portions in the microwave or warm the whole dish in the oven at 300°F until heated through. Note: The custard may soften slightly upon reheating, but the flavors will still be delicious.
Essential Equipment Guidance
For this recipe, a large skillet for browning the eggplant and a deep baking dish or tian are key. If you don’t have a tian, a 9×13-inch casserole dish works just as well. A whisk for the custard mixture and a sharp knife or mandoline for slicing vegetables will make the process smoother. Don’t forget: Paper towels for draining the eggplant are a must!
