I was a huge fan of Stewart's recipes — her slow-cooker mac and cheese was incredibly creamy, and her stovetop version had a delicious crust.After reading through Garten's recipe for baked mac and cheese, I noticed that it called for similar ingredients and followed similar steps to Stewart's stovetop recipe. I was eager to see how the chefs' recipes would compare, and which one would edge out the other as the best baked macaroni and cheese recipe.Though Martha Stewart's and Ina Garten's macaroni and cheese recipes are slightly similar, the biggest difference between them is that Stewart calls for four different kinds of cheese and adds sauteed onion to the dish.You can find the full recipe here.I chose a medium-size pot to make the cheese sauce in. The recipe calls for a quarter-cup of diced yellow onion.The recipe says to sauté the onions until they become translucent, which should take about five minutes. It took quite a bit of effort to hand-grate the cheeses. It was also difficult to measure out each cheese exactly, so I ended up guestimating somewhat.However, in the end, I had the right amount of each cheese to make the sauce, plus some cheese left over to sprinkle over the mac and cheese before putting it in the oven. It took about five minutes to cook the noodles, as they're supposed to be a little undercooked before going in the oven. It quickly thickened the onions and butter mixture. Per the recipe's instructions, I stirred the onions, flour, and butter together and left it for a few seconds until the mixture began to bubble in the pot.After a few minutes, the mixture had begun to thicken. After stirring the cheese sauce until all the ingredients were completely melted and combined, it was time to add it to the macaroni.However, the steps were easy to follow and I was able to sit down once the mac and cheese was ready to be put in the oven.After scooping my macaroni and cheese out of the pot and into the dish, I realized I had a lot left over. I could have easily filled another 3/4-ounce dish. You can use homemade breadcrumbs per the instructions from the slow-cooker version, or you can use store-bought in a pinch. I didn't have a food processor available to make homemade breadcrumbs but found that the store-bought kind didn't negatively affect my end result, and I was happy to cut out a step and save myself some dishes.The top layer of macaroni and cheese had a delicious, lightly browned crust, while underneath the macaroni and cheese was still perfectly creamy. It was enough to feed about four people, though I could have fed more if I had more dishes to bake the rest of the leftover macaroni.The macaroni and cheese was really flavorful, with a slightly smoky taste.The recipe only uses two types of cheese — extra-sharp cheddar and Gruyere — making this recipe a little less time-consuming and expensive to make. Perhaps to make up for less cheese, the recipe uses more butter and milk than Martha Stewart's version.You can find the full recipe here.Two tablespoons are reserved for the end, so you start off by melting 6 tablespoons in a pot on the stove. It's important to melt it at a low heat — you don't want the butter to burn or boil.The recipe calls for a pound of macaroni or cavatappi pasta. The celebrity chef also recommends adding oil to the pot of boiling water, which prevents the pasta from sticking to the bottom.After the butter was done melting, I added in a half-cup of all-purpose flour. The key is to whisk the mixture together until it has no clumps.Meanwhile, in a separate pot, I began heating up a quart of milk.The next step was whisking it together until the ingredients were fully combined.While the mixture was off the heat, I started grating my extra-sharp white cheddar cheese. The recipe calls for 8 ounces, which ended up being the entire package. It took a while to grate, so I was thankful that I had bought pre-grated Gruyere cheese.I seasoned the pot of cheese sauce with nutmeg, salt, and pepper. Ina Garten's recipe uses similar seasonings to Stewart's, save for the cayenne pepper that Stewart uses.This was another slight difference between the two recipes.After my noodles were cooked, I poured the cheese sauce over them and mixed it all together with a wooden spoon.I scooped the mixture into a baking dish and waited for the oven to finish pre-heating to 375 degrees Fahrenheit. I made one side of my dish with tomatoes and one without so I could see which one I preferred.The recipe calls for homemade breadcrumbs, but I opted to use the same store-bought ones I used in the Martha Stewart version for the sake of a fair comparison.The tomatoes were slightly roasted.The Ina Garten version tasted like an adult-friendly version of a childhood favorite, while the Martha Stewart version was more classic. The tomatoes added a ton of tart flavor to the dish and a unique texture, but I was torn over which I preferred.Both recipes have their high points, but I couldn't ignore the fact that the Ina Garten recipe was cheaper due to the fact I only needed two kinds of cheese. It was also dramatically easier to make. With the Stewart version, I had to prep onions and grate four kinds of cheese, for not that much more flavor in the end.If I was to choose which one to make again, I would definitely opt for the Ina Garten macaroni and cheese.
