Recipe Instructions

Step 1

Meanwhile, bring a large pot of lightly salted water to a boil. Cook spaghetti in the boiling water, stirring occasionally, until tender yet firm to the bite, about 12 minutes. Drain and set aside.

Step 2

Add spaghetti sauce, diced tomatoes, and broth; stir to combine. Nestle tuna steak into the middle of the sauce. Cancel Saute function. Close and lock the lid. Select high pressure according to manufacturer's instructions; set timer for 12 minutes. Allow 10 to 15 minutes for pressure to build.

Step 3

Release pressure carefully using the quick-release method according to manufacturer's instructions, about 5 minutes. Flake tuna apart with a fork. Add olives, capers, anchovy paste, herbes de Provence, and cayenne. Stir to combine and serve over hot cooked spaghetti.

Step 4

Turn on a multi-functional pressure cooker (such as Instant Pot) and select Saute function. Heat olive oil in the pot. Add onion and garlic; saute until softened and fragrant, about 4 minutes.
