- Preheat the oven to 425°F (220°C). Line a large baking sheet with parchment paper. 
- Place the broccoli florets on the prepared baking sheet. In a small bowl, whisk together the olive oil, lemon juice, salt, and pepper. Pour this mixture over the broccoli, tossing to coat the florets evenly.  
- Arrange the broccoli in a single layer on the baking sheet and bake for 20–25 minutes or until slightly charred. 
- While the broccoli is roasting, bring a large pot of salted water to a boil. Add the cavatappi pasta and cook according to the package directions. Reserve 1 cup of the pasta water before draining the pasta. 
- To a large nonstick skillet over medium-low heat, add olive oil. Once hot, add the minced garlic and sauté for about 1 minute. 
- Reduce the heat to low. Then, add the ricotta cheese and Parmesan cheese to the skillet, stirring to combine. Stir continuously for 2–3 minutes, or until the cheese melts.  
- Add the lemon juice, kosher salt, black pepper, and crushed red pepper, stirring well. 
- Gradually stir in ½ cup of the reserved pasta water, mixing until the sauce is well combined. If you prefer a thinner sauce, add more pasta water as needed. (I added ½ cup more pasta water, for a total of 1 cup.) 
- Add the cooked pasta and roasted broccoli to the skillet, tossing to coat evenly with the sauce. 
- Garnish with parmesan cheese and crushed red pepper.
