Key Ingredients
- Italian sausage meat (800g): Choose well-seasoned meat from a butcher, preferably a pork-veal blend for best flavor
- Zucchini (2 large): Select firm, glossy specimens of medium size for even cooking
- Heavy cream (160g): Full-fat cream delivers the richest sauce texture
- Dijon mustard (1 tsp): Traditional Dijon provides the perfect balance of heat and flavor
- Cheese blend (150g): Combine aged Gruyere and Parmigiano-Reggiano for optimal melting and flavor
Step-by-Step Instructions
- Preparing the Sausage:
- Crumble sausage meat into a cold pan. Cook over medium heat, stirring frequently. Add fresh thyme sprigs and bay leaf. Continue cooking until lightly golden. Drain excess fat carefully. Season with freshly ground pepper.
- Preparing the Zucchini:
- Wash and dry zucchini thoroughly. Trim ends and slice thinly using a mandoline. Layer slices on paper towels. Sprinkle lightly with salt to draw out moisture. Let rest 15 minutes. Pat dry thoroughly.
- Making the Tomato Sauce:
- Sauté minced onion in olive oil until soft. Add minced garlic and tomato paste. Pour in peeled tomatoes and water. Season with herbs de Provence. Add a pinch of sugar to balance acidity. Simmer gently for 20 minutes.
- Making the Mustard Sauce:
- Whisk heavy cream until smooth. Gradually blend in warmed milk. Incorporate mustard to taste. Season with salt, pepper and nutmeg. Sauce should be creamy but maintain body.
- Assembling the Lasagna:
- Preheat oven to 180°C/350°F with fan. Butter a large baking dish generously. Spread a thin layer of tomato sauce. Layer lasagna sheets without overlapping. Distribute one-third of the sausage mixture. Add a layer of zucchini. Pour mustard sauce over. Sprinkle with cheese. Repeat layers three times. Top with remaining cheese blend.

The mustard sauce brings a special depth to this dish, providing a gentle warmth that enhances both the vegetables and meat. Even picky eaters consistently enjoy this unique combination of flavors.
This lasagna represents the perfect fusion of traditional Italian comfort food and French culinary innovation. The addition of Dijon mustard to the cream sauce transforms a familiar dish into something uniquely memorable. It demonstrates how crossing cultural boundaries in cooking often produces the most satisfying results.
