📸 Step-by-Step Cooking Guide

🥦 1. Prep the Veggies

Chop broccoli, slice carrots, halve cherry tomatoes, and dice peppers and zucchini.
Tip: Keep veggie chunks medium-sized to avoid mushiness after baking.

🥗 2. Arrange in Baking Dish

Spread veggies in an even layer in your greased baking dish.
Optional: Toss with a drizzle of olive oil for extra richness.

🧀 3. Mix Creamy Herb Sauce

Whisk eggs with cream/milk, chopped herbs, salt, pepper, and half the cheese.
Tip: Fresh dill adds a surprisingly delicious kick here.

🫙 4. Pour Sauce Over Veggies

Slowly pour the mixture evenly across the top to coat all the veggies.
Don’t worry if it doesn’t submerge everything—it will settle while baking.

🔥 5. Top with Cheese and Bake

Sprinkle more cheese on top and bake for 20–25 minutes at 375°F until golden.
Tip: Broil the last 2 minutes for extra crisp topping.
