A creamy cheese sauce perfect for drizzling over broccoli!
In a small saucepan, melt butter over medium heat. Add flour and whisk until combined. Allow to bubble for 1-2 minutes, but do not allow to brown.
Add milk a generous splash at a time, whisking after each addition until all of the milk has been incorporated. Allow the sauce to bubble for 5-7 minutes, just until slightly thickened.
Remove from heat and stir in the cheddar. Once the cheese is melted, stir in salt and pepper. Serve right away.
