Ingredients

Servings 6
  • 4 cups vegetable broth
  • 1 cup polenta (coarse cornmeal)
  • 1 tablespoon olive oil
  • 1 small onion, finely chopped
  • 3 garlic cloves, minced
  • 10 oz fresh spinach, washed and chopped
  • 1 can (14 oz) artichoke hearts, drained and chopped
  • 1 cup shredded mozzarella cheese
  • 1/2 cup grated Parmesan cheese
  • 1 cup cream cheese, softened
  • 1/2 cup milk (or plant-based milk for dairy-free option)
  • 1/2 teaspoon salt
  • 1/4 teaspoon black pepper
  • 1/4 teaspoon crushed red pepper flakes (optional)
  • 1 tablespoon fresh parsley, chopped (for garnish)

Instructions

  1. Preheat the oven to 375°F (190°C).
  2. In a large oven-safe skillet or sauté pan, heat olive oil over medium heat. Add chopped onion and garlic and cook until softened and fragrant, about 3-4 minutes.
  3. In a medium saucepan, bring vegetable broth to a boil. Gradually whisk in polenta and reduce heat to low. Cook, stirring frequently, until polenta thickens and becomes tender, about 15 minutes. Remove from heat.
  4. Stir in cream cheese, milk, salt, black pepper, and crushed red pepper flakes (if using) into the cooked polenta until creamy and smooth.
  5. Add the chopped spinach and artichoke hearts to the sauté pan with onions and garlic. Cook, stirring occasionally, until spinach is wilted and most moisture has evaporated, about 5 minutes.
  6. Fold the spinach and artichoke mixture into the creamy polenta, then stir in half of the mozzarella and half of the Parmesan cheese.
  7. Spread the polenta and vegetable mixture evenly in the oven-safe pan. Sprinkle the remaining mozzarella and Parmesan cheese evenly on top.
  8. Bake uncovered for 25-30 minutes, or until the cheese on top is melted, golden, and bubbly.
  9. Remove from the oven and let rest for 5 minutes. Garnish with fresh parsley before serving.
  10. Serve warm directly from the pan or portion for meal prep. This dish keeps well refrigerated for up to 4 days and freezes beautifully.

Frequently Asked Questions

This creamy one-pan spinach and artichoke polenta bake is versatile and adaptable for various dietary needs:

  • Vegetarian & Gluten-Free: Naturally vegetarian and gluten-free optional. Use certified gluten-free polenta and vegetable broth to ensure gluten-free status.
  • Dairy-Free Alternatives: Substitute cream cheese, mozzarella, Parmesan, and milk with plant-based versions like cashew cream cheese, vegan mozzarella, nutritional yeast (for cheesy flavor), and almond or oat milk.
  • Vegan Option: Use vegan cream cheese and dairy-free cheese alternatives, ensuring broth is fully plant-based with no animal ingredients.
  • Low-Sodium: Select low-sodium vegetable broth and reduce added salt to fit heart-healthy diets.
  • Additional Vegetables: Enhance flavor and nutrition with mushrooms, zucchini, or bell peppers without complicating the one-pan method.
  • Herbs & Spices: Boost flavor by adding fresh basil, oregano, or smoked paprika for a subtle twist, while keeping the recipe simple.

These substitutions maintain the dish’s family-friendly appeal, suitability for meal prep, and comforting, easy casserole style.

Pan Or Pot Required

This Creamy One-Pan Spinach and Artichoke Polenta Bake requires two essential pieces of cookware to create its creamy, layered flavor while keeping cleanup easy for busy home cooks.

  • Medium Saucepan: Perfect for gently cooking the polenta in vegetable broth. Frequent stirring ensures a smooth, thick consistency without sticking or burning.
  • Large Oven-Safe Skillet or Sauté Pan: Ideal for sautéing aromatics like onions and garlic, wilting spinach and artichokes, folding in creamy polenta, and baking. This pan lets you transition seamlessly from stovetop to oven, preserving flavors and achieving a golden, bubbly cheese crust.

Choose durable cookware such as cast iron or stainless steel with sturdy handles to guarantee even cooking and attractive browning. This recipe fits perfectly into PanPotPlates’ casseroles category, making it a simple, family-friendly, and comforting once-pan meal.

Using these two cookware essentials maximizes kitchen efficiency, simplifies cleanup, and makes this dish perfect for meal prep and reheating leftovers.

Cookware Size Guidance

For this one-pan casserole serving 6, select a large oven-safe skillet or sauté pan with a capacity of at least 4 to 5 quarts (3.8 to 4.7 liters). This size comfortably accommodates the polenta base, spinach, artichoke hearts, and cheese layers, providing enough space to mix ingredients without spilling and ensuring even baking and browning.

If you don’t have a skillet of this size, substitute with a 9x13-inch (23x33 cm) baking or casserole dish at least 2 inches deep to prevent overflow during baking.

Using the right size cookware ensures even cooking, a nicely browned top, and the perfect creamy texture characteristic of Italian-inspired casseroles.

Cookware Swap Guidance

This creamy spinach and artichoke polenta bake is designed as a convenient one-pan casserole, ideally baked in a large oven-safe skillet or sauté pan that transitions from stovetop to oven. If you lack an oven-safe skillet, consider these alternatives:

  • Oven-Safe Casserole or Baking Dish: Sauté onions and garlic in a regular pan, then combine all ingredients in a ceramic, glass, or enameled cast-iron casserole dish for baking. This suits meal prep and family-friendly casseroles.
  • Cast Iron Skillet: A cast iron skillet not oven-safe is still excellent due to heat retention and stovetop-to-oven versatility, great for even heating in comfort food recipes.
  • Ovenproof Dutch Oven: Offers ample depth and great heat retention for stovetop cooking and baking casseroles. Ensure lid and handles are oven-safe.

For cooking polenta, a medium saucepan (nonstick or stainless steel) is essential. Standard sauté pans or skillets work fine for pre-sautéing before assembling the bake.

Choose cookware that fits your kitchen and keeps this easy, family-friendly recipe practical. These substitutes help maintain the rich flavors and creamy texture while adapting to your tools.

Leftovers Quality

This creamy one-pan spinach and artichoke polenta bake stores excellently as leftovers and is perfect for make-ahead meals. Refrigerate uneaten portions within two hours in airtight containers to keep freshness and prevent spoilage. Properly stored leftovers remain good for up to 4 days in the fridge.

For longer storage, freeze the casserole up to 3 months. Portion into individual freezer-safe containers or cover the entire dish tightly with foil and plastic wrap. To reheat from frozen, thaw overnight in the refrigerator, then warm in the oven at 350°F (175°C) for 20–30 minutes until heated through and bubbly. For refrigerated leftovers, reheat covered in the oven or microwave, stirring occasionally for even warming.

Because this recipe features a creamy, cheesy polenta base with spinach and artichokes, gentle reheating preserves its creamy texture and prevents drying. Adding a splash of milk before reheating can restore creaminess if needed. These storage and reheating tips make this casserole ideal for quick weeknight dinners, meal prep, and reducing food waste.
