Preheat your oven to 400°F and line a small baking sheet with parchment paper.
Toss the sliced zucchini, diced red pepper, onion, and celery with olive oil and a pinch of salt, then roast for 15 minutes until tender.
While vegetables roast, sauté the minced garlic and shrimp in a non-stick skillet over medium heat until the shrimp are pink and opaque.
Prepare the gluten-free lasagna noodles according to the package instructions until they are al dente.
In a small bowl, combine the crushed tomatoes with the lactose-free heavy cream, dried oregano, sea salt, and black pepper to create a blush sauce.
In a small oven-safe baking dish, spread a thin layer of the tomato sauce on the bottom.
Layer a noodle, followed by a portion of the roasted vegetables, sautéed shrimp, and a sprinkle of the mozzarella, gouda, and feta cheeses.
Repeat the layers until all ingredients are used, finishing with a generous layer of the three cheeses on top.
Lower the oven temperature to 375°F and bake the lasagna for 20 to 25 minutes until the cheese is melted and the sauce is bubbling.
Let the lasagna rest for 5 minutes before serving to allow the layers to set.
