Great pasta dish!! I had not cooked with Havarti cheese before and was absolutely thrilled with the result! It melted nicely into the pasta and contributed great flavor! To suit my family I used only half of the crushed red pepper which resulted in a hint of heat - perfect for us. I also measured the juice from the tomatoes, added water to equal 2 cups of liquid, and also added chicken bouillon -all in place of the chicken broth. I did make it ahead and baked it later - that worked well according to your directions. Delicious! We'll make this one again. Thanks Skooch.
