Slice the zucchinis in half lengthwise and scoop out the center with a spoon to create boats. Place them in a baking dish and set aside.
In a pot of boiling water, blanch the cauliflower florets for about 5 minutes until tender. Drain and transfer them to a food processor.
Add the heavy cream, Parmesan cheese, minced garlic, Italian seasoning, salt, and pepper to the food processor with the cauliflower. Blend until smooth and creamy. This will be your Alfredo sauce.
In a skillet, heat olive oil over medium heat. Add the shrimp and season with salt and pepper. Cook for about 2-3 minutes on each side until pink and opaque. Remove from heat.
In a large bowl, mix the cooked shrimp with the Alfredo sauce until well combined.
Spoon the shrimp Alfredo mixture into each zucchini boat generously.
Bake in the preheated oven for 20-25 minutes or until the zucchinis are tender yet still holding their shape.
Once done, remove from the oven and let them cool slightly. Garnish with chopped parsley before serving.
Notes
Feel free to add more vegetables to the filling if desired.
