1 medium head cauliflower, cut into bite-sized florets
•
5 cloves garlic, peeled and smashed
•
2 tablespoons olive oil, or more to taste
•
¼ teaspoon salt
•
¼ teaspoon ground black pepper
•
1 (16 ounce) package penne pasta
•
1 cup grated Parmesan cheese
•
¼ cup seasoned bread crumbs
•
1 teaspoon ground cayenne pepper
•
2 tablespoons salted butter
•
¼ cup lemon juice
Instructions
Preheat the oven to 425 degrees F (220 degrees C).
Toss cauliflower with garlic cloves, olive oil, salt, and pepper in a large bowl. Spread out in an even layer on a baking sheet.
Roast in the preheated oven, tossing at least twice, until cauliflower is tender, about 30 minutes.
Meanwhile, bring a large pot of lightly salted water to a boil. Add penne and cook, stirring occasionally, until tender yet firm to the bite, about 11 minutes.
Mix Parmesan cheese, bread crumbs, and cayenne pepper together in a bowl; set aside.
Drain pasta, reserving 1/2 cup cooking water. Transfer pasta to a serving bowl and add cauliflower and butter. Stir in cooking water, a little at a time, until desired creaminess is reached. Add lemon juice and bread crumb mixture, toss, and serve.
