Toss noodles with creamy sauce, sweet peas and white beans for this cool-weather pasta. On the side, roasting broccoli with some garlic and olive oil makes it crisp on the outside and tender on the inside.
Toss broccoli and garlic (portion for broccoli) in olive oil and paprika. Spread on a sheet pan. Season with some salt. Roast, shaking pan halfway through cooking, until broccoli is tender, 20 to 25 minutes.
While broccoli roasts, heat a large saute pan over medium heat. Add butter and swirl it in the pan until it melts. Add flour to melted butter and stir until no dry spots of flour remain. Add stock and garlic. Simmer until stock reduces by about half, 3 to 4 minutes. Add heavy cream, beans and peas and continue cooking until it forms a thick, creamy sauce. Remove from heat and stir in lemon zest and mustard. Season with some salt and pepper.
When broccoli is tender, toss with lemon juice.
Reheat noodles if made ahead.
Toss sauce with noodles and serve with parsley on top. Enjoy broccoli on the side.
