Stuffed Shells Florentine

Stuffed shells florentine are the lighter-than-expected Italian baked pasta that makes weeknight vegetarian dinners feel substantial. Jumbo shells get filled with a mix of cottage cheese (instead of heavier ricotta), sautéed mushrooms, onions, frozen spinach, and egg substitute, then baked under a layer of jarred marinara until bubbling.

The cottage cheese swap is what cuts calories without sacrificing creaminess; when baked, cottage cheese behaves almost identically to ricotta while bringing slightly more tang and significantly less fat. Egg substitute in place of whole eggs keeps the dish cholesterol-friendly, and the mushroom-onion-garlic trio adds umami depth that pure cheese stuffings miss.

Sautéing the aromatics in margarine softens and concentrates their flavors before they meet the cheese mixture. This step is often skipped but makes a real difference, because raw onions in baked pasta stay sharp and crunchy rather than melting into the background.

Kitchen Tips

• Cook jumbo shells just until al dente, then rinse under cold water. Overcooked shells tear when you try to stuff them.
• Thaw and squeeze the frozen spinach in a clean towel. Wet spinach makes the filling watery.
• Drain cottage cheese in a fine mesh strainer for 10 minutes if it seems loose.
• Stuff shells with a small piping bag or zip-top bag with the corner cut off for cleaner filling.

Variations

• Swap cottage cheese for ricotta or a mix of ricotta and mozzarella for richer traditional florentine.
• Add crumbled Italian sausage or diced pancetta to the mushroom mix for a meaty version.
• Top with shredded mozzarella or grated parmesan during the last 10 minutes of baking for a golden crust.
