Broccoli Garlic Angel Hair Pasta

Heat butter and oil in a large skillet over medium heat until hot. Add garlic and cook, stirring often, until soft but not browned, 1 to 2 minutes. Sprinkle in pepper flakes and season with salt.

Pour chicken stock into the skillet and bring to a simmer. Add broccoli stems and simmer until tender, 10 to 12 minutes; add more stock if mixture starts to dry out.

While the broccoli stems are cooking, bring a large pot of lightly salted water to a boil. Add pasta and cook, stirring occasionally, until almost tender, about 4 minutes.
