Ingredients You’ll Need

Let’s look at the ingredients and how they work together to create this Simple Zucchini Dill Casserole:

• 1 cup baking mix – Acts as the structure and binds the ingredients. Substitute with homemade Bisquick or gluten-free blend if needed.
• 1/2 cup shredded Parmesan cheese – Adds salty, umami depth. You can use cheddar for a sharper bite or mozzarella for a milder, gooier option.
• 1 tbsp dried dill – The star herb that gives this zucchini gratin with dill its fresh, herby character. Sub with 3 tbsp fresh dill if available.
• 1 tsp salt + 1/8 tsp black pepper – Brings out all the flavors. Adjust to taste.
• 4 large eggs, slightly beaten – Provides richness and binding power.
• 1/2 cup canola oil – Keeps the casserole moist and soft. Olive oil is a great substitution.
• 3 cups diced zucchini – The main vegetable, tender and mild. No need to peel unless skin is tough.
• 1 large chopped onion – Adds savory depth and texture. Red onion adds sweetness; white onion brings sharpness.

How to Make Simple Zucchini Dill Casserole (Step-by-Step)

Step 1: Combine Dry Ingredients

In a large mixing bowl, whisk together the baking mix, Parmesan cheese, dill, salt, and pepper until evenly distributed.

🔬 Why this works: This ensures the herbs and salt are evenly mixed before adding wet ingredients, avoiding clumps.

Step 2: Add Eggs and Oil

Make a well in the center of the dry ingredients and pour in the eggs and canola oil. Stir until smooth and thick.

👃 What to look for: A lightly glossy batter that’s cohesive but not runny.

Step 3: Fold in the Vegetables

Stir in the diced zucchini and chopped onions. Mix gently but thoroughly.

🧠 Tip: Let the mixture sit for 5 minutes before baking to allow the baking mix to absorb moisture and create fluffier texture.

Step 4: Pour and Bake

Grease a 1.5-quart casserole dish and pour in the mixture. Bake at 375°F (190°C) for 25–30 minutes until the top is golden and a toothpick inserted comes out clean.

🔥 Sensory cue: The edges should be browned and pulling away slightly from the sides.
