Steps

1. Thinly slice 1/2 onion.
   🕒 00:51
2. Make a cut at the base of 1/2 head broccoli (approx. 80g) and separate into florets. If making smaller florets, cut into the stem side.
   🕒 01:13
3. Peel and cut 2 small potatoes (approx. 200g) into 2cm cubes.
   🕒 01:30
4. Cut 1 chicken breast (approx. 250g) in half horizontally and then slice thinly into bite-sized pieces.
   🕒 02:00
5. Lightly season the thinly sliced chicken breast with salt. Dust with 1 tbsp potato starch. [Secret Tip!] Coating the chicken with potato starch protects it, resulting in a very tender and smooth texture.
   🕒 02:21
6. Melt 30g butter in a frying pan.
   🕒 03:08
7. Once the butter has melted, add the thinly sliced onion and sauté until softened and sweet.
   🕒 03:21
8. Add 2 tbsp all-purpose flour and sauté briefly until no powdery residue remains.
   🕒 03:43
9. Gradually add 600ml milk, stirring well and repeating the process of adding more milk as it thickens.
   🕒 04:01
10. Once the mixture is stable, add the remaining milk and mix. [Secret Tip!] With a small amount of flour, it's easy to make without lumps.
    🕒 04:31
11. Season with salt to taste.
    🕒 04:52
12. Add 1 clove grated garlic for richness. [Secret Tip!] Since we are using chicken breast, garlic is used to enhance the flavor.
    🕒 04:58
13. Add the cubed potatoes and simmer while stirring, until a skewer can easily pass through them. You can also add consommé granules to your liking.
    🕒 05:04
14. Add the chicken breast dusted with potato starch.
    🕒 05:47
15. Add the separated broccoli florets and cook until everything is done.
    🕒 06:08
16. If the mixture becomes too thick, add a little milk and simmer until it reaches the desired consistency.
    🕒 06:17
17. Mix half of the 80g pizza cheese into the sauce. [Secret Tip!] Adding cheese first will increase the sauce's creaminess and richness.
    🕒 06:39
18. Taste and adjust seasoning with salt.
    🕒 07:05
19. Transfer the finished gratin to oven-safe dishes.
    🕒 07:13
20. Top with the remaining pizza cheese as desired.
    🕒 07:27
