This creamy Cajun-spiced pasta is loaded with savory peppers and onions, white beans and a generous portion of greens to make this a healthy, though indulgent, weeknight dinner.
Bring a saucepan of water to boil. Salt generously and add pasta. Cook until al dente, tender but not soggy. Drain and reserve 1/2 cup (118 mL) of pasta water (for 4 servings; adjust accordingly if customizing).
While pasta cooks, heat a skillet or saute pan over medium-high heat. Add oil. When oil begins to shimmer, add onions, bell peppers, zucchini and garlic. Saute until tender, ~4 minutes. Add Cajun spice mix and saute until it coats vegetables and becomes fragrant, ~2 minutes.
To the vegetables, add spinach, tomato paste, heavy cream and reserved pasta water (if pasta is still cooking, just use a measuring cup to scoop water out of the pot) and stir to combine. Simmer until liquids reduce to a thick sauce and spinach is wilted, 1 to 2 minutes. Toss in pasta and white beans and stir until sauce coats pasta. Season with some salt and pepper.
Serve pasta with fresh black pepper cracked over top and enjoy!
