Beef bourguignon already has beef and a rich sauce, but lasagna wasn’t where I expected to see it end up. One home cook took the French stew in that direction, using it as the basis for a lasagna instead of serving it in a bowl.

Reddit user u/Lhollusaurus said she made beef bourguignon lasagna over the weekend and described the result as “divine.” When another cook asked how she prepared the stew for the pasta, she revealed one important step: she added roux to thicken it.
Thicken the Bourguignon Before Building the Lasagna
Beef bourguignon comes with plenty of cooking liquid, which creates a problem when moving it from a bowl to layers of pasta.
Her solution was roux.
The commenter doesn’t give measurements or explain how much liquid she reduced before adding it. She only confirms that roux went into the bourguignon to make it thicker before the dish became lasagna.
That distinction matters. She wasn’t pouring a thin stew between sheets of pasta.
The Beef Becomes the Lasagna Filling
Once thickened, beef bourguignon can take the place normally occupied by a meat sauce.
Instead of starting another filling from ground beef and tomato sauce, the idea uses the cooked beef and its sauce as the foundation for the lasagna.
The Reddit discussion doesn’t specify whether she shredded the beef, left it in chunks, or broke it apart before layering. It also doesn’t say whether vegetables from the bourguignon went into the finished lasagna.
What we know is that the bourguignon was thickened with roux and then used to make the lasagna.
A Potato Masher Came Into the Process Too
The cook shared one more detail after explaining the roux.
She said she gave the mixture a light press with a potato masher.
That could help break down larger pieces before they go between pasta sheets, though she doesn’t explain her reason for doing it. The source also doesn’t say how fine she made the filling.
The Rest of the Lasagna Wasn’t Shared
There isn’t a complete beef bourguignon lasagna recipe in the discussion.
The commenter doesn’t give the number of pasta layers, cheese choices, béchamel or ricotta, baking temperature, pan size, or oven time. Filling those details in would mean creating a recipe she never posted.
What makes the idea worth saving is the part she did explain: beef bourguignon doesn’t have to return to the table as another bowl of stew. Thickening it with roux gives the saucy beef enough body to take on another role.
Instead of reheating the bourguignon as it is, she turned it into the filling for lasagna.
Would you turn leftover beef bourguignon into lasagna, or keep the two dishes separate?
