After a few attempts of trying to perfect a rye version of the famed Jim Lahey No Knead Bread recipe, I ended up switching to an entirely new recipe (albeit another favorite). That recipe - Simple Crusty Bread by Jeff Hertzberg - has been a perfect compliment to rye flour, and I've made the recipe several times over the summer.
To make this bread, I've halved the recipe and included approx. 1/2 cup of rye flour to 2 3/4 cup of AP flour (I may increase the rye moving forward, but the rye flavor still comes through at this ratio). Baking the bread for the full baking time (30 - 31 minutes) seems key as I initially was baking it for 27 - 28 minutes, which led to a slightly softer crust as the bread cooled.
Another important tip is to try to let this bread cool as much as possible to "sweat out" the internal moisture and not make the crust / interior too soggy while cutting into it while warm.
This can be hard to do when the bread smells so wonderfully delicious out of the oven, but letting it cool for a few hours definitely seems key to get that nice firm crust coupled with a soft interior. This is definitely a new MadhuKnitsandCooks favorite that will take me through the seasons!
