An Elegant OMAD Meal with Only 9g Net Carbs

Christmas is the season for celebrating, and nothing says “celebration” quite like a rich, perfectly prepared Beef Wellington. But who wants to make a giant, messy loaf just for one person? And how can you keep it keto?

This Keto Beef Wellington Bite is the answer. I’ve taken the most elegant holiday meal and shrunk it down to the perfect, satisfying size for your One Meal A Day (OMAD) plate.

We use two keto secrets here: a small, tender filet mignon (the “bite”) and a simplified, single-serving Fathead Dough wrapper that bakes up beautifully golden and flaky. It’s the ultimate zero-waste, single-serving splurge.

Christmas Keto Beef Wellington Bite Recipe

Ingredients

1. The Beef Bite

• 1 (4–5 oz) center-cut beef filet mignon (or tenderloin cut), trimmed
• 1 Tbsp unsalted butter or ghee
• Salt and black pepper

2. Mushroom Duxelles

• 2 oz cremini mushrooms, finely chopped
• 1 small shallot, finely diced
• 1 clove garlic, minced
• 1 tsp fresh thyme leaves
• 1 tsp brandy or dry sherry (optional, for flavor; cooks off)
• 1 Tbsp cream cheese, softened

3. Single-Serve Fathead Dough

• 1/3 cup shredded mozzarella cheese, low moisture
• 1/2 Tbsp cream cheese
• 2 Tbsp almond flour, super-fine
• 1/4 tsp xanthan gum (optional, helps elasticity)
• 1 small egg yolk (for the dough)

4. Finish

• 1 egg, whisked (for egg wash)¹
• 1 tsp Dijon mustard (optional, for coating beef)

Directions

1. Sear the Beef

1. Preheat oven to 400°F (205°C).
2. Pat the beef filet completely dry and season generously with salt and pepper.
3. Heat butter/ghee in a small oven-safe skillet over high heat.
4. Sear the filet for 60 seconds on each side to create a deep crust. This is crucial for flavor and texture.
5. Remove the filet from the pan and let it cool completely on a plate.
6. Optional: Once cool, brush the filet with a thin layer of Dijon mustard—this adds a tangy layer of flavor.

2. Make the Duxelles

7. In the same skillet, melt a pat of butter (if needed). Add the chopped mushrooms, shallots, garlic, and thyme. Cook over medium heat for 5–7 minutes, stirring until all liquid has evaporated and the mixture is very dry.
8. Optional: Stir in the brandy/sherry and let it cook off entirely (about 30 seconds).
9. Remove from heat. Stir in the softened cream cheese until the mixture is thick and cohesive. Set aside to cool.

3. Make and Wrap the Dough

10. In a microwave-safe bowl, combine the mozzarella and cream cheese. Microwave in 30-second bursts until completely melted and smooth (about 60–90 seconds total).
11. Stir in the almond flour, xanthan gum (if using), and egg yolk until a workable dough forms.
12. Place the dough between two sheets of parchment paper. Roll it out into a thin sheet large enough to completely wrap the filet (about 5×7 inches).
13. Spread the cooled mushroom duxelles evenly over the rolled dough.
14. Place the seared filet in the center of the dough.
15. Carefully fold the dough tightly around the filet, trimming off excess dough and pinching the seams shut. Turn seam-side down.

4. Bake

16. Place the wrapped Wellington Bite on a small baking sheet.
17. Brush the entire surface generously with the whisked egg wash. Score the top lightly with a knife for decoration.
18. Bake for 15–20 minutes for medium-rare, or 20–25 minutes for medium. The pastry should be deeply golden brown.
19. Let rest for 5 minutes before slicing and serving.

🔪 Marco’s Tips: Mastering the Single-Serving Splurge

• Temperature is Key: Use a meat thermometer if you have one! Aim for an internal temperature of 130°F (54°C) for medium-rare. Since the filet is small, it cooks fast!
• The Power of Parchment: Do not try to roll the Fathead Dough without parchment paper. It will stick everywhere.
• Make it OMAD Complete: Serve this with a single portion of rich, buttery Keto Garlic-Parmesan Green Beans or a small serving of celeriac mash to make it a full, decadent meal.

💡 Marco Ketson Global Flavors Deep Dive: What is Duxelles?

The rich, savory heart of this Wellington is Duxelles (pronounced doo-SELL).

It’s a classic French technique: a mixture of finely minced mushrooms, shallots, and herbs, cooked until all moisture has completely evaporated.

Why It’s Keto Essential

• Umami Bomb: The drying process intensely concentrates the mushroom’s natural savory flavor (umami) for ultimate satisfaction.
• Zero-Carb Binder: It creates a thick, cohesive paste, perfectly replacing high-carb breadcrumbs or flour thickeners in your fillings.

Marco’s Pro Tip: Do not rush the cook time! The Duxelles must be completely dry—if it’s wet, the pastry will turn soggy. You should be able to scrape a dry trail across the bottom of the skillet.
