            <div >
              <label  for="{{kitchen.id}}">

It worked for me, Form Control pass value. How is it done here link

    // Get selected Kitchen id
    this.selectedKitchenId =
      this.persistenceService.get('selectedKitchenId') ?? null;


  initializeForm(): void {
    this.form = this.formBuilder.group({
      kitchenType: new FormControl(this.selectedKitchenId, Validators.required),
    });
  }

                type="radio" 
                [id]="kitchen.id"
              >
              <strong>{{selectedKitchenId === kitchen.id}}</strong>
            </div>
          </div>
        </div>
        <div >
          <button type="submit" 
          >
            Tęsti
          </button>
          <button
            [routerLink]="['/']"
            class='btn btn-block mx-auto buttonBack'>
            <i ></i>
            Grižti
          </button>
        </div>
      </form>

This is how easy template-driven is

Fixed some best-practices for you

To get the values, just use like this on TS file:

goToNextStep(form) {
   const {kitchenType} = form.values
}
