Chef’s Serving Suggestions


These baking directions will result in well-done beef tenderloin. If you desire less than well-done, cook beef separately and serve together.
This is a great recipe to use if you have baked a spaghetti squash.
To bake the spaghetti squash, cut in half, brush each side with 1 tsp olive oil, sprinkle with a pinch of sea salt and bake cut side up on a broiler pan or in a baking dish at 350° for about 1 hour. When cooked, the spaghetti squash will pull apart easily with a fork.
