Cook bacon, stirring often, until browned around edges and fat is rendered, about 4 minutes. Add breadcrumbs and cook, stirring often, until brown and crisp, about 5 minutes. Transfer breadcrumb mixture to paper towels and let cool slightly. Toss in a medium bowl with chile, thyme, and lemon zest; set aside.

Reduce heat to low, cover skillet, and cook until tender, about 5 minutes. Uncover skillet, add reserved leaves and 1 Tbsp. lemon juice, and toss to combine. Cover skillet and cook, tossing occasionally, until leaves are bright green and just wilted, 4–5 minutes. Uncover; add remaining 1 Tbsp. lemon juice and season with salt.
