Mastering Beef Wellington

Most beef Wellington recipes come together like this: Coat a well‑seared beef tenderloin in duxelles (finely chopped sautéed mushrooms), wrap it in crepes or thinly sliced prosciutto, top it with smears of liver pâté or slabs of foie gras, and encase everything in fancifully decorated pastry. Then slide it into the oven, fingers crossed that the beef emerges juicy and pink inside a crisp, golden crust.

I spent three days (and a staggering $600) evaluating five such recipes, and none fully justified the time or expense. However, there were bright spots: One Wellington featured deeply savory duxelles; another boasted medium-rare, juicy beef; and yet another had a beautifully crisp, golden crust.

Coming up with my own version was a tall mountain to climb, so I tackled the easy stuff first. I salted the beef overnight to enhance its flavor and ditched the dull crepes in favor of umami-rich prosciutto. I fortified the duxelles with shallots and a splash of Madeira and cooked it long enough to drive moisture from the mushrooms, concentrating their earthiness. Finally, I jettisoned the pâté, since its liver-y taste competed with rather than complemented the beef, and instead brushed the beef with Dijon mustard to add a complex kick. In the end, the package was so improved that I found I could skip the usual step of searing the meat.

Next, the pastry. Most modern recipes call for store-bought puff pastry, but the frozen dough often emerged from its package cracked where it had been folded and, as it warmed, was easy to tear. Once cooked, it slumped in spots and never fully crisped. However, one recipe from the innovators at ChefSteps promised success with pâte brisée, an all‑butter dough often used for tarts. Sure enough, this dough was easy to work with, even as I decorated the top of the Wellington with slender dough strips arranged on an elegant diagonal. Unlike the doughs of many other recipes I tried, which crumbled when sliced, this buttery, flaky crust was just sturdy enough to pass the slicing test.

My last challenge was simple to understand but hard to solve. Here’s the deal: Pastry requires high heat to set its shape, crisp, and brown. A beef roast, on the other hand, benefits from a low-and-slow approach to produce medium-rare meat from edge to center. A sample cooked in a 425-degree oven yielded a crisp, golden crust but overdone beef; 325 degrees produced rosy beef but slack, pale pastry.

It wasn’t until I called a side-by-side tasting that I had a breakthrough. I served the first roast while the other one waited nearby, and a lengthy discussion kept me from promptly returning to the second roast. When I finally sliced into it, the meat was gray, not pink. I had expected a certain amount of carryover cooking, but I was surprised at how significant the effect was here: This meat had been pushed to 150 degrees, well beyond my 130-degree target.

So why not make carryover cooking work for me instead of against me? Thus began a series of tests in which I pulled the Wellington from the oven at progressively lower temperatures. In the end, I landed on a technique in which I blasted the Wellington in a 450-degree oven for 45 minutes until the crust was crisp, flaky, and golden and then removed it when the meat registered a mere 85 degrees. During a 45-minute rest on the counter, the temperature of the roast steadily climbed to 130 degrees.

It was Wellington perfection: When sliced, the roast exuded hardly any juice, and the well-seasoned, medium-rare tenderloin encased in savory duxelles, salty prosciutto, and crisp pastry was a sight to behold. I beamed as I served it with a luxe sauce of heavy cream, brandy, and piquant green peppercorns, knowing that it had been well worth the effort.
