I’m still playing around with my sous vide and picked up an eye round on closeout to try something new. The “French Connection” in the title isn’t a crime movie reference — sous vide itself is a French technique, literally translating to “under vacuum,” and this cook leans into that fully: French method, applied to a cut that’s about to become sliced roast beef.
Eye round is a lean, tough cut that benefits enormously from a long, low sous vide cook. The best approach I could find was 24 hours in the water. I seasoned it with salt, pepper, and garlic and bagged it.

I set the unit to 129°F and the timer for 24 hours.

Water ran a little low around the 20-hour mark, so I topped it off and it came back up to temp quickly.
Since I planned to finish this one on the smoker rather than just sear it, I shocked it in cold water first to bring the temperature down.

Straight out of the bag it looked gray, as sous vide meat often does before any color develops.

I seasoned it again while I got the smoker ready.

Prepping for the Smoker
I run a Weber Smokey Mountain, and since I still had leftover coals from a previous cook, I lit about 20 fresh ones in the chimney and added them in, since this was going to be a short smoke.

I placed the roast on the smoker that was running about 225

I added some cherry wood chunks to the coals for smoke flavor.

I monitored the internal temp, aiming to bring it back to the same 129°F it had reached in the sous vide bath, then pulled it. I then covered it in olive oil, so it would sear.

The Sear
I heated up the cast iron to 600 degrees before dropping the eye round in for the sear.

I seared it for about 5 minutes total, making sure all sides got good color.

I removed it, covered it, and let it rest about 10 minutes before slicing.

Result
Start to finish, the whole process took about 30 hours. It turned out great — very tender and flavorful, especially for a cut that’s naturally lean and tough.
