Soften the Base: Heat 2 tablespoons olive oil in a large skillet over medium heat. Add 1 medium onion and sauté for 3 minutes until soft. Stir in 3 tablespoons tomato paste, 1 - 2 cloves garlic (grated), and ½ teaspoon red pepper flakes.Cook for 1 minute—the paste should turn a deep, dark red.
Simmer the Beans: Add 2 cans butter beans (drained), ½ teaspoon salt, and 2 twists black pepper. Stir to coat them in the red sauce.Pour in 1½ cups vegetable broth and ½ teaspoon dried oregano. Let it simmer (gentle bubbles) for 5 - 6 minutes. The sauce will thicken naturally as the beans release their starch.
Wilt the Greens: Stir in ½ cup sun-dried tomatoes and 3 cups baby spinach. Cook for 2 more minutes until the spinach shrinks down and looks bright green.
Finish and Serve: Turn the heat completely off and move the pan to a cool burner. Stir in ⅓ cup grated parmesan cheese until melted, then fold in the ½ cup Greek yogurt and ½ teaspoon lemon zest to keep the sauce silky and prevent curdling. Scatter over 1 handful fresh basil leaves and serve immediately with crusty bread.
Parmesan cheese –> Pecorino Romano or nutritional yeast.
Greek yogurt –> Low-fat Greek yogurt or Skyr.
Oregano & Basil –> Fresh parsley or marjoram.
Tips
"Off-Heat" Rule: Turn the stove off before adding yogurt so the sauce stays silky and doesn't separate.
Sauté Paste: Cook the tomato paste for 1 minute to remove the raw taste and deepen the color.
Garlic Bread Hack: Serve with toasted sourdough rubbed with a raw garlic clove for a huge flavor boost.
Fix Thick Sauce: If it sits and gets too thick, stir in 1–2 tablespoons of water or broth to make it glossy again.
Mixed Diets: Use this as a delicious "saucy side" for grilled chicken or salmon.
Zest Last: Add lemon zest at the very end to keep the flavor bright and fresh.
Storage: Fridge for up to 3 days; reheat gently on the stove (don't boil!). Do not freeze, as the yogurt texture will become grainy and split when thawed.
