Beef tenderloin is extra special. True to its name, this cut is luxuriously tender—perfect for impressing your dinner companion (and yourself). Here, it’s seared and then drizzled with an ultra-savory shallot pan sauce. Like any great steak-centric meal, however, the sides might just steal the show. We’re serving up creamy Parmesan mashed potatoes and roasted carrots and parsnips tossed with nutty brown butter. Team Add Butter to Everything!
