Step-by-Step Cooking Directions

  1. Infuse the Milk
    In a saucepan over medium heat, combine 500 ml milk and the clove-studded onion. Bring to a gentle boil, then remove from heat. Cover and steep for 10 minutes to infuse aromatic onion–clove flavor.

  2. Prepare the Béchamel Base
    In a clean pot, melt 50 g butter over medium heat. Add 3 tbsp flour and stir continuously for 2–3 minutes until the mixture smells nutty but not browned. Gradually whisk in the infused milk (discard onion and cloves) until smooth. Stir in ½ tsp nutmeg, salt, and pepper. Cook for another 2 minutes until thickened. Remove from heat and set aside.

  3. Par-Cook the Vegetables
    Bring a pot of salted water to boil. Add diced potatoes and cook for 5 minutes, then add zucchini slices and cook for an additional 2 minutes. Drain and set aside in a colander to wick off excess moisture.

  4. Sauté Aromatics & Meat
    In a large skillet, heat a drizzle of olive oil. Sauté chopped celery, carrot, and diced bell pepper for 5 minutes until softened. Add 250 g minced beef, breaking it up with a spatula. Season with 1 tsp salt, black pepper, garlic powder, paprika, and basil. Cook until beef is browned and no longer pink. Stir in 2 tbsp tomato sauce, then remove from heat.

  5. Custard Binder
    In a small bowl, whisk together 2 eggs and 2 tbsp flour until smooth. Slowly whisk into the warm béchamel to create a cohesive custard-like sauce.

  6. Layer the Casserole
    Preheat oven to 200 °C (350 °F). Grease a deep baking dish with olive oil. Spread half of the par-cooked potatoes and zucchini in an even layer. Top with the beef mixture, then another layer of vegetables. Pour the béchamel–egg mixture evenly over the top. Sprinkle 200 g mozzarella and chopped parsley and dill.

  7. Bake to Perfection
    Bake on the center rack for 20 minutes at 200 °C, then reduce heat to 180 °C (350 °F) and continue baking for another 20–25 minutes until the top is golden and bubbling. During the last 5 minutes, brush the surface with 50 g melted butter for extra richness.

  8. Rest and Serve
    Let the dish rest 10 minutes to set. Optionally garnish with finely chopped sautéed onion. Cut into squares and serve warm.

Health Benefits

The use of whole milk and minimal added sugar keeps the dish naturally nourishing.

Serving Suggestions

Light Salad Side: Serve with arugula, cucumber, and cherry tomato salad dressed in lemon vinaigrette.
Crusty Bread: Offer warm bread or garlic toast to soak up extra sauce.
Wine Pairing: A medium-bodied red like Merlot or a crisp Chardonnay complements the richness.
Yogurt Dip: A side of herbed yogurt or tzatziki adds cool contrast.

Common Mistakes to Avoid

Skipping Par-Cook: Undercooked potatoes or zucchini can remain firm; always par-boil.
Thin Sauce: Rushing the béchamel can leave it runny. Cook until the sauce coats the back of a spoon.
Dry Meat: Over-browning without moisture results in dryness; the tomato sauce helps maintain juiciness.
Crowded Dish: Overfilling can prevent even baking; use a suitably sized dish.

Pairing Recommendations

Beer: A light amber ale balances creamy layers.
Non-Alcoholic: Sparkling water with mint or a lemon-ginger iced tea refreshes the palate.
Side Dips: Serve with spicy harissa or chutney for extra zing.

Cooking Tips

Uniform Slices: Cut vegetables evenly for consistent cooking.
Heat Control: Keep béchamel on medium-low to avoid scorching.
Herb Freshness: Add fresh dill and parsley at the end of baking to preserve aroma.
Make It Lighter: Use skim milk and reduce cheese by 25% for fewer calories.

FAQ

  1. Can I use chicken instead of beef?

    Ensure potatoes and zucchini are well-drained before layering, and use a hot oven.

  3. Is it freezer-friendly?
    Assemble without baking, wrap tightly, and freeze up to 2 months. Bake from frozen, adding 10–15 minutes.

    It should coat the back of a spoon and leave a clear line when you run your finger through it.

  7. Can I skip the infused milk step?
    You can steep onion and cloves directly in the béchamel, but infusing separately ensures even flavor.
