Pat steak dry and sprinkle all over with a scant
1/2 tsp salt and
1/4 tsp pepper. Heat oil and butter in a 10-inch heavy skillet over
medium heat until foam subsides, then cook steak, turning once, until
well browned, 7 to 10 minutes total for medium-rare. Transfer to a
cutting board and let stand, uncovered, 10 minutes.
Add shallot to skillet and cook, stirring, until
3 minutes. Add cream, blue cheese, and spinach and cook, scraping up
brown bits from bottom of skillet and turning spinach with tongs,
until spinach is wilted, about 2 minutes.
Stir in lemon juice and salt and pepper to taste.
