Instructions
Step 1: Prepare the Oven
Preheat your oven to 400°F (200°C). Lightly grease a medium-sized baking dish with olive oil.
Step 2: Caramelize the Onions
Heat olive oil in a skillet over medium-low heat. Add the sliced onions and cook for 12–15 minutes, stirring occasionally, until soft, golden, and caramelized.
Add the minced garlic and cook for another 30–45 seconds until fragrant.
Step 3: Prepare the Kale
Add the chopped kale to the skillet. Cook for 2–3 minutes, stirring gently, until the leaves begin to soften.
Add the cherry tomatoes and cook for another 2 minutes.
Step 4: Add the White Beans
Stir in the drained cannellini beans, vegetable broth, oregano, thyme, smoked paprika, red pepper flakes, salt, and black pepper.
Mix gently until everything is evenly coated in the flavorful seasoning.
Step 5: Add the Cheese
Stir in ½ cup mozzarella and ¼ cup Parmesan cheese. Add the fresh lemon juice and mix gently.
Transfer the mixture into the prepared baking dish and spread it evenly.
Step 6: Add the Topping
Sprinkle the remaining mozzarella and Parmesan cheese over the top.
Arrange a few extra cherry tomatoes and caramelized onion rings on top for a beautiful presentation.
Step 7: Bake Until Golden
Bake uncovered for 20–25 minutes, until the tomatoes are softened, the cheese is melted and bubbly, and the edges are lightly golden.
For an extra golden top, broil for 1–2 minutes, watching carefully.
Step 8: Garnish and Serve
Remove from the oven and let rest for 5 minutes.
Garnish with fresh parsley, thyme, black pepper, and a drizzle of olive oil. Add toasted walnuts if desired.
Serve warm with crusty bread, toasted sourdough, or a fresh Mediterranean salad.
