Recipe Comments & Reviews

Terrific recipe. Made it just as is except I topped it with buttered planko crumbs. I've been making tuna casseroles for 65 years and this is by far the best one I've ever tasted. Took a serving to my daughter at work, for lunch and she said awesome, Will use this recipe often.
I made it exactly as stated- except no cheese - not big cheese lovers here. It's really good and will be made often.
Had to sub out a few things (olives for peas, grilled red peppers in oil for fresh red bell pepper, cream of chicken instead of mushroom and added about 6oz. of noodles instead of 4) but it turned out GREAT! Recipe is so flavorful and creamy! Big hit all around. My new go-to tuna casserole recipe because it's a great base recipe that can have lots of substitutes.
I made this basic recipe but used Vital Choice Tuna. The very best and safest tuna available.
Did not use the soup as i don't use canned soups...too many additives. Make my own cream sauce with a vaariety of wild mushrooms. I also use 1 quarter cup of dry Sherry. I also add a couple of tablespoons of chopped green wild olives. Freshly ground pepper and Celtic salt. I used the Land Of Lakes cheese...Swiss not low fat. There is little difference in the to as to cholesterol levels so going natural is the thing to do. I also add a cup of Leeks, white part only sauteed along with the mushrooms. Sprinkled the top with purple potato shreds for color and a lot of potassium.
Wonderful served with chilled frisee salad and a very good Pinot.
I eliminated the peas and bell peppers, doubled the amount of Land O Lakes cheese and substituted french fried onions, which I sprinkled over the top for the last ten minutes of cooking time, for the potato sticks. We absolutely LOVE this recipe!!!
FABULOUS comfort dish. Quite yummy. This one definitely goes into my "Tried and True" recipe book.
It was really good! Have made it to recipe and a few different ways. Don't need to add extra salt - tuna has enough. Substitute whole wheat egg noddles or mix whole wheat egg noddles with regular egg noodles to get more fiber. Add LOL low fat or fat free sour cream or LOL yogurt to cut calories. Another idea for a great topper but adds the calories- melt 2 TBS LOL butter, add equal parts bread crumbs and grated parmesan or asiago cheese and top casserole. Hope these ideas help you enjoy as much as my family does!

January 6, 2016 by Land O'Lakes Test Kitchen

Chocolate’s complex flavor brings out the sweetness and tanginess of fruit, mellows the heat of peppers, and comes alive when introduced to a little bit of salt. The real question should be, “What can’t you dip in chocolate?” More ...
