Low FODMAP baked mac and cheese with ham

Oh guys, this recipe makes me so happy! It is not healthy, it doesn’t contain enough veggies, but it is so incredibly good. A low FODMAP baked mac and cheese with ham and mushrooms.

When we were kids, my sister and I were crazy about this dish. My mum used to make a large oven dish full of this and we usually completely finished it with the four of us.

Crazy enough, I totally forgot about the existence of this recipe for the last few years, but now I suddenly remembered it.

I asked my mum for the recipe and when my mother-in-law and sister-in-law were visiting from Slovenia, their first time in Holland, I served them this meal.

It might not be the most Dutch recipe that you can imagine, but it kind of is. Macaroni casseroles are very popular in the Netherlands and we used to eat them quite often when I was young.

Everybody loved it and I have already made the casserole two more times in the last two weeks, so that says enough.

This recipe doesn’t contain a lot of vegetables, I only added some canned mushrooms. Because of that I like to serve the mac and cheese with a big salad on the side, so that my meal still contains enough veggies.

The dish itself is traditionally like this, without extra vegetables and very cheesy. But if you would like to add some veggies you can of course. Broccoli or paprika goes very well with it.

Low FODMAP baked mac and cheese with ham and mushrooms.The best macaroni casserole ever! Guilty, but so yummy! Gluten-free and lactose-free.


  • 300 g gluten-free macaroni
  • 200 g canned mushrooms*
  • 300 g ham, in cubes
  • 200 g grated cheese
  • 1 tsp oregano
  • 1/2 tsp ground paprika
  • Pepper and salt
  • A large oven dish

For the bechamel sauce

  • 40 g butter
  • 50 g gluten-free flour
  • 500 ml lactose-free milk


  1. Pre-heat the oven to 180 degrees Celsius.
  2. Cook the macaroni according to the instructions on the package.
  3. Melt the butter in a small pan. Add the gluten-free flour and the oregano. Stir well and heat through for a minute.
  4. Add the lactose-free milk little by little. Add a splash of milk and stir well with a whisk. Then add another splash of milk. Continue until you have used all of the milk and you have a smooth sauce. Bring the sauce to a boil and leave to boil for about 3 minutes while you stir regularly.
  5. Season the bechamel sauce with paprika powder, pepper and salt. Stir 175 gram of the cheese into the sauce. Save the other 25 grams to sprinkle on top of the oven dish later. Leave the sauce to simmer for one more minute and then turn off the heat.
  6. Rinse the mushrooms and drain them.
  7. Put the macaroni together with the ham and the mushrooms in the oven dish.
  8. Pour the bechamel sauce on top and stir together. Sprinkle the rest of the cheese on top.
  9. Put the oven dish for 15 minutes in the oven and then serve immediately.

    This sounds great. Only problem in US we use pounds and ounces. Will have to google. Lol

  • Elissa says:

    What type of cheese do you use for the ‘grated cheese’? Does it need to be specifically lactose free?

  • Cettina Sciberras says:

    I did it today and I really liked it. I used cheddar cheese did I do right?

  • Anne says:

    I’ve made this dairy free, too. I use dairy free butter, So Delicious dairy free cheese and almond milk.
    Grandkids also liked it much better with sliced hot dogs instead of the ham.

  • Nunya says:

    what part of this is low FODMAP

    mushrooms are not low. fodmap
    random grated cheese so a hard cheese like parmesan would be the only option here

    this should be listed as gluten-free but not low. FODMAP.

    was really excited to find a low FOD map recipe and this is not it.

      If you are going to write a very judgy comment, please also get your facts straight. I base my recipes on information from the Monash University FODMAP app, the app from the creators of the FODMAP diet. I specifically mention canned mushrooms in the recipe. The Monash app states that canned mushrooms are low FODMAP in a serving of 70 grams per serving and only contain a moderate amount of FODMAPs at 200 grams or more per serving. So the serving in this recipe is low FODMAP. Next to that it is also not true that only a hard cheese like parmesan is low FODMAP. If you check the app you will see that a very large array of cheeses have low FODMAP servings. I use grated gouda cheese for this recipe most of the time and this type of cheese hardly contains any lactose and is therefore safe use on the FODMAP diet.

      Don’t forget that there is a person on the other end side of the screen. Feedback is always welcome, but can also be delivered in a friendly way.
