Prep

  1. Lentils – Rinse lentils and soak in water overnight or for at least 8 hours. (Can be done 1 day ahead)
  2. Garlic / Onions - (If prepping right before cooking, get oven heating before continuing with prep.) Prep as directed. Store separately. (Can be done up to 5 days ahead)
  3. Parsley / Lemons - Prep as directed. Store separately. (Can be done up to 2 days ahead)
  4. Fish - Rinse and pat dry. Season with some salt and pepper.

Make

  1. Drain lentils and discard water.
  2. Heat oven to 425F / 218C degrees.
  3. Heat a Dutch oven over medium-high heat. Add oil and then onions to heated oil. Saute until starting to soften, 2 to 3 minutes.
  4. Add drained lentils, garlic, stock, thyme (portion for lentils), and salt. Cover and bring to a simmer. Simmer, uncovered, until lentils are tender, ~10 minutes. Add some more stock or water if liquid cooks off before lentils are tender. (Note: If you didn’t soak your lentils before starting, increase the amount of stock you add by 50% and plan to simmer for 25 to 30 minutes. Keep an eye on them and add additional liquid if needed.)
  5. While lentils simmer combine thyme (portion for fish), parsley, lemon juice, capers, mustard, and creme fraiche.
  6. Place fish in a baking dish. Spread creme fraiche mixture over top of fish. Bake, uncovered, for 12 to 15 minutes depending on thickness of fish.
  7. Return to lentils. When lentils are tender and all of the liquid has been absorbed, add peas (no need to defrost them first) and spinach. Cook for another 2 to 3 minutes. Remove from heat and season with some salt and pepper.
  8. Serve fish over lentils with lemon wedges on the side. The mustard / crème fraiche turns into a natural sauce. Enjoy!

It was better than we expected, but looks unappetizing and is a bit blah. The sauce was great - glad I doubled it though, because everything else was quite dry.

Family loved it! I used fresh thyme, double the amount suggested, next time I would add a bit more fresh thyme, 1/4 cup more peas and cook the lentils for less time.

This is good, but a bit boring. I think I would have liked more mustard in the sauce.

The lentils were our favorite part. The fish grew on us after a couple bites. Our sauce did not melt or fall of the fish like some mention in their reviews - couple of thoughts on this. 1 - buy good creme fraiche, cheap won't get you the same flavor or texture. 2 - make your sauce a little on the thicker side to stick to the fish. 3 - add extra capers if you like them!

I made this with lentils and it was a nice different taste and fairly easy. We always love capers.

Topping didn't spread well. This was okay.
