This homemade copycat of Olive Garden's Con Zucchini brings the warmth of Italian dining to your kitchen. The dish features a robust, slow-simmered sauce built from sautéed onions, minced garlic, and a mix of chopped and quartered fresh mushrooms for varied texture. Crushed and diced tomatoes meld with capers, black olives, and aromatic herbs like oregano, basil, and fennel seeds to create a deep, savory flavor profile. The sauce is ladled over hearty rigatoni, which holds the juices beautifully. Topped with lightly browned, lengthwise-sliced zucchini, this meal offers a perfect balance of earthy vegetables and comforting pasta. It is a satisfying, plant-based main course that feels indulgent yet wholesome, perfect for a cozy weeknight dinner or a casual weekend gathering.
