Spaghetti With Braised Kale

Directions

1. 1
   Rinse kale. Drain; transfer to bowl with some water still clinging.
2. 2
   Heat 2 tablespoons olive oil in heavy large pot over medium heat. Add chopped onion and cook until soft and translucent, stirring occasionally, about 6 minutes. Add sliced garlic and sprinkle with salt; cook until onion is golden brown, stirring occasionally, about 5 minutes. Add kale and remaining 1 tablespoon olive oil and toss until wilted, about 3 minutes. Cover pot and reduce heat to medium-low. Continue cooking until kale is very tender, stirring occasionally and adding water by teaspoonfuls if dry, about 20 minutes.
3. 3
   Meanwhile, cook spaghetti in medium pot of boiling salted water until tender but still firm to bite, stirring occasionally. Drain, reserving 1/4 cup cooking liquid. Add cooked spaghetti to kale mixture in pot. Add lemon juice and 2 tablespoons reserved cooking liquid; toss to combine, adding more liquid by tablespoonfuls if dry. Sprinkle spaghetti with grated Parmesan cheese and serve.
