This was delicious! I'm not sure who would think this was bland, unless you skipped the first few steps and just threw it all in a crock pot. The cooking of the mushrooms and shallots gives you the fond you need to make it tasty and should not be skipped.
I did the crock-pot method and did find the whole process a little time consuming, but worth it in the end. I also did not add the lemons or the zest, but did add the lemon juice in the final steps. This would be great over a biscuit as well! I will definitely make this again.
