Pan-Seared Beef Tenderloin with Creamy Spinach and Crispy Potatoes

Beef tenderloin wrapped in prosciutto and seared until golden, served over a silky creamy spinach base with crispy pan-fried potato slices. This elegant plated dish combines tender, juicy beef with earthy spinach and buttery potatoes for a restaurant-quality meal. The prosciutto adds salty richness while the beef reaches a perfect medium-rare in the oven. Best for special dinners or when impressing guests, this dish balances protein, greens, and starch on one plate. The key to success lies in not washing potatoes after slicing to preserve starch for crispness, wrapping beef tightly in prosciutto for even cooking, and timing each component so everything finishes simultaneously. Serve with balsamic reduction or sweet chilli sauce for depth.

Tips
Do not rinse potato slices after cutting. The surface starch is essential for achieving golden-brown, crispy edges when pan-frying. Rinsing creates a sticky, soggy texture instead.
Wrap beef portions snugly in prosciutto before searing. The cured meat protects the exterior from drying out and adds salty flavor that seasons the beef from outside in.
Time each component to finish within 2-3 minutes. Sear beef last so it stays warm; spinach and potatoes hold temperature well and can be kept warm on the stove.
Good to Know
Cover and refrigerate beef separately from vegetables up to 2 days. Spinach best used within 1 day.
Wrap beef in prosciutto and refrigerate up to 8 hours. Prepare spinach base up to 6 hours ahead and reheat gently. Slice potatoes just before cooking.
Serve immediately while beef is warm and potatoes remain crispy. Pairs well with dry red wine, roasted vegetables, or a simple green salad.
Common Mistakes
Wash potatoes after slicing to avoid soggy, sticky texture that won't crisp properly.
Wrap beef loosely to avoid uneven cooking and heat loss during searing.
Cook all components at different times to avoid cold or overcooked elements at plating.

FAQ
Can I make this ahead of time?
Wrap beef in prosciutto up to 8 hours ahead and refrigerate. Make spinach base 6 hours early; reheat gently. Slice potatoes only just before cooking to prevent oxidation and ensure crispness.
What if I don't have sour cream?
Use heavy cream or creme fraiche in equal amounts. Heavy cream creates a lighter sauce with less tang. Creme fraiche provides similar richness with a slight sour note.
How long should beef cook in the oven?
At 220 degrees Celsius, cook approximately 7-8 minutes for medium-rare. Thicker portions may need 9-10 minutes. Use a meat thermometer: 50-55 degrees Celsius for rare, 55-60 for medium-rare.
