Fish and seafood are wonderful proteins for low-carb, keto, slow-carb, and Mediterranean lifestyles. The problem is many people don’t like fish or find it too bland when made without breading. Enter this quick and easy almond-crusted cod with Dijon mustard. No more bland!

What Kind of Fish Can Be Substituted for Cod?
This recipe is one of the low-carb fish dinners that highlight cod, but any white fish could be used. I prefer the thicker filets like halibut and cod, but we’ve tried it with sunfish and crappies and it works just fine. I do live in the state of 10,000 lakes after all. Crappies (aka croppies) are just a bit more abundant here than cod and halibut!
Which Diets Work with Almond-Crusted Cod?
I’ve been on a high-protein-low-carb diet for years now (alternating between nuanced versions of slow-carb, low-carb, & ketogenic and most recently focused on Pesco Mediterranean), and most of the high-protein recipes associated with these diets (lifestyles) focus on chicken, beef and pork proteins.
After working with over 400 people as a diet and health coach, I have learned a ton from both research and hands-on experiences with a wide variety of clients. While most “diets” work for weight loss if they involve a decrease in calories, not all of them benefit health.
Fish can be substituted as a protein source for low carb and slow carb, but it is a little more problematic with keto, as keto favors proteins higher in fat.
I have recently become a huge proponent of the Pesco Mediterranean diet for two reasons:
- It offers the health benefits of the Mediterranean diet; health benefits that have been thoroughly researched and documented year after year.
- It is sustainable, which is key to long-term weight loss. You are not excluding any particular food group (except maybe processed foods if you call that a food group). Many diets work in the short term, but the sustainability of the weight loss over time is a major problem that leads to a lot of frustration. Too much frustration often leads to “giving up”, which is a big hit to self-confidence.
The recipe below (inspired by Eating Well magazine) was quick and easy, but it also packed a lot of flavor. In addition, it is compliant with the various low-carb, slow-carb, keto, and Pesco Mediterranean diets.
If you are experimenting with the nuances of the various low-carb diets and want more information on how they differ this low-carb vs slow-carb vs carb-cycling article is a great summary.
Basics of the Pesco Mediterranean Diet
All in all, the Pesco Mediterranean diet is not that much different than the well-known Mediterranean diet. The basic tenets include:
- Plenty of plant-based fruits and vegetables.
- Generous use of extra virgin olive oil.
- Fish and seafood replace red meat as the protein source, with beans and chicken adding a secondary protein source.
- Intermittent fasting as a component. There is not currently a rule on which method of intermittent fasting. I am a proponent of 16/8 (eating within an 8-hour window and fasting the rest of the time).
Seafood and fish are an integral part of the Pesco Mediterranean Diet. This article will fill you in on the details of the Pesco Mediterranean Diet to see if it might be something you want to try.
Up the Flavor of White Fish with Low Carb Breading
I have posted several recipes for low-carb fish dinners (see below for links). Many of them use salmon and scallops, however, and cooking with white fish (cod, flounder, tilapia, etc.) can sometimes result in a bland and uninspired flavor profile.
Here are some recipes using white fish that are deliciously robust in flavor:
- A low-carb breading recipe.
- Mexican Fish Veracruz
- Spicy Seared Tuna Dinner
- Catfish Cakes with 2 Dipping Sauces
- Mexican Fish Stew
- Pan-fried fish with Plum Sauce (Pesco Mediterranean only)
- Brazilian “Shrimp in Pumpkin” dish (Camarão na Moranga)
- Variations on Keto or low-carb breading mixes to enhance seafood
For enhancing fish (or vegetables), fresh pre-made spice blends can offer a whole world of alternatives. Old Bay seasoning is also a well-known spice blend for fish and seafood.
