Kristin Cavallari's Must Haves: From a Luxe Espresso Machine to Rao's Marinara Sauce

Cavallari uses her Uncommon Beauty Dust Bag ($5) often, especially when she's traveling. "I just throw all of my beauty stuff in there, and it's just easy to close up really quickly," she says. The nifty and versatile pouch is made from 100 percent cotton and can hold more than just beauty essentials, including jewelry, keys, and any other small travel essentials.

Pro Tip: She loves that this is flexible enough to fit into awkward spaces. "Because it's not a hard shell, you can kind of smush it into places in your suitcase if you need to," she points out.

Another travel must have she adores is her Street Level The OG Reversible Tote ($60). "You can literally throw everything in there, and it'll fit," she says — plus it's lightweight, and it has comfy straps so no matter how jam-packed it is, it won't dig into your shoulders. Cavallari can fit everything from her laptop to a ton of snacks and even a to-go meal in this huge tote bag. She also carries a little beauty bag with all her essentials, big headphones, a book, and a water bottle. "It really will hold everything that you need for a flight," she says.

Pro Tip: This reversible model is perfect for work and travel, plus it comes with a detachable coin purse.

Cavallari takes her coffee seriously, and it's not complete without her Rocket Espresso R58 Cinquantotto Espresso Machine ($3,300). "It's a whole ritual for me in the morning. I love making a legit espresso," she says. "I feel fancy when I do it." Making good use of the espresso machine's milk steamer, she loves using it to make lattes with Brazil nut milk and cashew milk. Noting that this espresso machine is an investment, she only recommends it for true coffee connoisseurs.

Cavallari not only appreciates its function but also loves how it looks on her counter. "It's not so big that it takes up a ton of room. I have like a little wet bar off of my kitchen, which is where I have all my coffee stuff. It's all my alcohol and my coffee. It's my favorite area of the house," she says.

Pro Tip: Cavallari loves to top off her coffees with a little bit of maple syrup. "It just gives it that little smoky, sweet, smoky flavor," she says.

Cavallari loves putting a few drops of the Young Living Lavender Essential Oil ($27, originally $36) on her pillow and feet right before bed. "I've been doing it for years. I sleep like a baby when I do it. I love it," she says. She adores the "nice and easy" scent lavender exudes, saying, "It just kind of relaxes you immediately."

Pro Tip: Lavender oil isn't just for nighttime. "If you're just having like a stressful day where you just need to take a minute, then this would be a good one to grab," Cavallari says.

You can find several jars of Rao's Homemade Marinara Sauce ($9) in Cavallari's pantry. "It's the only store-bought sauce that I will buy because it's the closest to that authentic homemade pasta sauce. My dad is 100 percent Italian, and he was the one who initially told me about Rao's Homemade," she says. Cavallari is a big fan of the brand, so much so that she partnered with the brand to create a few recipes incorporating the sauces in her cookbook. One of her favorite recipes is her baked ziti.

Pro Tip: "You can throw it in any recipe if you wanna just save time instead of making your own sauce, and you're not gonna lose any flavor," she says.
