Keto Beef Wellington Preparation

Recipe Details

The Keto Beef Wellington is a dish steeped in history, traditionally known for its rich flavors and luxurious presentation. The original Beef Wellington is said to have been named after the Duke of Wellington and has graced dinner tables for special occasions ever since. However, its classic pastry shell is far from keto-friendly. This is where our keto adaptation comes in, transforming the dish with a crust that’s just as satisfying, yet low in carbs.

This recipe is a labor of love and a celebration of high-quality ingredients. The beef tenderloin, known for its tenderness and flavor, is the star of the show. We enhance its natural savoriness with a touch of Dijon mustard, and then wrap it in a blanket of prosciutto, adding a salty, rich depth to the dish. The mushroom mixture brings an earthy complexity, while the almond and coconut flour crust provides a satisfying crunch without the carb overload.

As a keto enthusiast, you’ll appreciate that this dish is not only a feast for the eyes but also a powerhouse of nutrients. The high fat content from the olive oil, butter, and eggs aligns with the keto diet’s macronutrient ratios, helping to maintain ketosis. The beef tenderloin offers a substantial amount of protein, making this dish as nutritious as it is delicious.

The Method

The key to a perfect Keto Beef Wellington lies in the preparation and attention to detail. Start by preheating your oven to ensure a consistent cooking environment for the beef. Seasoning the beef tenderloin with just the right amount of salt and pepper will enhance its natural flavors without overpowering them. When searing the beef, aim for a high-quality crust; this Maillard reaction not only adds flavor but also helps to lock in the juices.

Brushing the seared beef with Dijon mustard is a step you do not want to skip. The mustard adds a tangy contrast to the richness of the meat and helps to marry the flavors of the beef with the mushroom and prosciutto layers. As for the mushroom mixture, be patient as you sauté them. Letting them cook down until they’re golden-brown will concentrate their flavor and prevent a soggy crust.

The dough for the crust is a delicate balance of almond and coconut flours, which can be tricky to work with due to the lack of gluten. Make sure the dough is pliable but not too sticky, and roll it out gently between two sheets of parchment paper to prevent tearing. The prosciutto and mushroom layers not only add flavor but also create a barrier that keeps the crust from getting soggy.

Wrapping the beef tenderloin requires a gentle touch. Ensure that the dough is sealed tightly around the beef to keep the juices in. When baking, keep an eye on the oven as almond flour can brown quickly. Use a meat thermometer to check for doneness to your preference, and remember to let the Wellington rest before slicing to allow the juices to redistribute.


Herb-Infused Crust

Infuse your crust with a blend of dried herbs such as rosemary, oregano, or basil for an aromatic twist. This will add another dimension of flavor to the crust, complementing the beef and mushrooms beautifully.

Spinach and Cheese

For a pop of color and a boost of nutrients, add a layer of wilted spinach and a sprinkle of feta or goat cheese between the beef and prosciutto. This variation introduces a creamy texture and a tangy taste that pairs wonderfully with the tenderloin.

Cauliflower Rice Duxelles

Replace the mushrooms with cauliflower rice sautéed with garlic and herbs for a duxelles-inspired filling. This alternative is perfect for those looking to add more vegetables to their meal while keeping the carb count low.


Understanding that not everyone has access to the same ingredients or may have dietary restrictions, here are some thoughtful substitutions to accommodate different needs while keeping the dish keto-friendly:

For the Beef Tenderloin

If beef tenderloin is out of reach, consider using a different cut of beef such as sirloin or ribeye. Just be mindful of the cooking times as these cuts may vary in thickness and tenderness.

For the Prosciutto

Should you not have prosciutto on hand, thinly sliced bacon or pancetta can serve as a suitable substitute. They will still provide the salty, fatty layer that complements the beef and helps to keep the crust in place.

For the Almond and Coconut Flour

For those with nut allergies, try using ground sunflower seed meal in place of almond flour. As for coconut flour, if it’s not your favorite, consider using more almond flour, but be aware that you may need to adjust the amount as coconut flour is more absorbent.
