Create a yummy wet rub in a medium mixing bowl by combining olive oil, cajun seasoning, salt, and pepper. For the cauliflower, slice it into 1-inch thick steaks. Then, place the cauliflower steaks on a parchment-lined sheet pan, brushing both sides with the wet rub.
Bake the Salmon and Vegetables
Next, quarter the baby Dutch yellow potatoes, toss them in the rub, and add them to the sheet pan, leaving space for the salmon. Bake the vegetables halfway. After the initial bake, season and add the salmon to the pan, flip the cauliflower and potatoes, then return it to the oven to bake.
Make the Dressing
Meanwhile, prepare a salmon sauce with Dijon mustard, honey, parsley, salt, and pepper. Once the salmon is cooked, brush it with the honey mustard sauce. Then, whisk mayonnaise, lemon juice, and chopped parsley for the dressing. Finally, garnish the plated dish with reserved parsley.

Hey Explorers! Get ready to launch on a culinary journey with the step-by-step photo instructions for the Baked Cajun Honey Mustard Salmon, Cauliflower Steaks, and Potatoes recipe below, with each image guiding you through the process. Enjoy!
Prepare the Vegetables
Begin by removing the outer green leaves of the cauliflower and rinsing the whole head.
Place the cauliflower on a cutting board with the stem side down. Using a sharp knife, make vertical slices that are about 1 inch thick. These slices will be your cauliflower steaks. Be mindful of the first and last slices, as they may not hold together well due to loose florets.
Then, cut each baby potato into quarters by cutting them in half and then in half again.
Combine the olive oil, Cajun seasoning, salt and pepper. To save on the amount usage of utensils, use the brush to mix the wet rub.
Brush the cauliflower and carefully turn with a flat spatula to coat the other side.
Then, add the potatoes to the bowl, toss them in the wet rub, and lay them on the sheet pan.
Prepare the parsley by simply picking from the tender short stems, rinsing, drying, and chopping.
Make the Sauce and Dressing
Using the same mixing bowl. Clean the bowl and make the dressing by whisking together the Dijon mustard, honey, and parsley with salt and pepper.
The vegetables and salmon will be ready when the salmon has reached an internal temperature of 145 degrees Fahrenheit using a meat thermometer and golden brown.
Remove the baked salmon and vegetables from the oven and brush the salmon filets with some of the sauce.
Finally, finish the dressing by whisking together mayonnaise, fresh lemon juice, and chopped parsley. For a more robust flavor, add lemon zest.

- Baby Dutch Yellow Potatoes - Use medium Yukon, russet, or sweet potatoes cut into skinny wedges to cook uniformly with the cauliflower. One medium potato should be enough for two servings.
- Low-Fat Mayonnaise - Try regular mayonnaise or substitute it with Greek yogurt or sour cream. Remember and don't get confused: Mayonaisse does not contain dairy, and it is dairy-free but not egg-free. If you are allergic to eggs, try vegan mayo.
- Fresh Parsley - If you do not have fresh parsley on hand, try dried parsley or add a small amount of Italian seasoning
- Honey - Use maple syrup; however, this may change the flavor a bit, but just might work!
Change Heat Level - Modify the recipe's heat level to your liking and learn more about the Scoville Scale and Chili Pairings. If you wish for your meal to be less spicy, try using all-purpose seasoning instead or a little bit of Memphis Rub dry seasoning.
It also has similar spices except for the smoky component, but it may work. And for more heat, try using hot honey, which is a prepared mixture of honey with chili peppers.
- Add More Vegetables - Try adding quartered Brussels sprouts, green beans, and/or zucchini.
- Salmon Bowl - Turn this into a bowl by making roasted cauliflower florets instead. Then, serve the salmon, cauliflower, and potatoes with shredded greens or white or brown rice. Try also adding more healthy protein, like chickpeas or white beans, to the sheet pan before baking. This would be a great addition to the rice/salad bowl.
Try Something Different - Substitute the Tuna for Salmon in the Healthy Poached Egg Avocado Rainbow Tuna Salad recipe.
- Medium Mixing Bowl - To make the wet rub, toss the potatoes and dressing to complete the meal.
- Sheet Pan - Use a half-sheet pan for a serving of two, like the Nordic Ware Baker's Half-Sheet pan. Why sheet pans? They cook food faster than a glass baking dish. But if you choose to use a baking dish, just watch and cook it a little longer.
- Parchment Paper - To place between the food and bakeware for easy cleanup and to prevent food from sticking to the pan.
- Turning or Fish Spatula - To assist with flipping the delicate cauliflower and serving the fish. Try the OXO Good Grips Stainless Steel Fish Turner. It's just always good to have one for jobs like this.
- Brush - Used to coat the cauliflower and salmon. I use a silicone pastry brush since it's easy to go from cold to hot meals without distorting the bristles. Try the OXO Good Grips Silicone Basting & Pastry Brush.
- Meat Thermometer - It is always great to have to cook food to their ideal temperatures to prevent drying out. And most importantly, to prevent food-borne illnesses. Try the ThermoPro Digital Meat Thermometer. To develop my recipes, I actually use the ThermoPro Wireless Meat Thermometer; it has a probe that you leave in the meat and will notify you when it reaches the ideal temperature.
Kitchen Must Haves - Find other tools I use here.
- Refrigerator - To store in the fridge, you can place the honey mustard salmon meal in a shallow 2-inch container to cool down quickly. Then, store it in an airtight container. As a result, the meal will last up to two days.
- Freezer - Follow the refrigeration process mentioned above. Then, place it in the freezer in a labeled, airtight container. Be aware that the cauliflower texture will change when placed in the freezer.
Air Tight Food Containers - I use Glass Food Storage Containers with a plastic clipping lid to store food. For example, I always suggest glass storage containers since you can microwave them and hold food without staining the container, and the glass keeps them at a more stable temperature, which keeps the food fresher longer.
For a moist and flavorful baked honey mustard salmon, avoid overcooking by removing it from the oven just as it easily flakes with a fork at the thickest part, ensuring a perfect, tender result every time.
Frequently Asked Questions
The key to perfectly baked salmon is to check for doneness by inserting a fork or the edge of a knife into the thickest part of the fillet. If the salmon easily flakes and appears opaque, it's done.
Keep in mind that the internal temperature should reach 145 degrees Fahrenheit (63 degrees Celsius) for optimal safety and flavor. Avoid overcooking to maintain the fish's moistness and delicate texture.
To prevent cauliflower steaks from becoming soggy during baking, make sure to pat the cauliflower slices dry with a paper towel before applying any oil or seasoning.
Excess moisture on the surface of the cauliflower can lead to steaming rather than roasting, resulting in a less crispy texture. Additionally, ensure that the oven is adequately preheated, and avoid overcrowding the baking sheet, allowing each steak enough space for proper caramelization.
