Spaghetti with Creamy Spinach Sauce

Instructions

1. Bring a large pot of lightly salted water to a boil.
2. Meanwhile, to make sauce, heat a large nonstick skillet over medium-high heat; add spinach and sprinkle with water. Cook, tossing, until spinach wilts down and becomes tender, about 3 minutes; remove cooked spinach from skillet. (If your skillet isn’t large enough, cook in 2 batches.) When spinach is cool enough to handle, squeeze out excess water.
3. Add pasta to boiling water and cook according to package directions.
4. While pasta cooks, heat oil in same nonstick skillet. Add onion, garlic, salt and pepper; cook over medium heat, stirring often, until onion is very tender and light golden, about 6 to 8 minutes. Stir in spinach; toss until mixed.
5. Drain pasta, reserving 1/2 cup of cooking water. Transfer pasta to a serving bowl; add spinach mixture and ricotta. Toss, adding 1/4 cup (or more) of reserved pasta cooking water to make a creamy sauce. Serve hot. Yields about 1 3/4 cups per serving.
